NAME
locale - subset of a user's environment that depends on language and
cultural conventions
DESCRIPTION
A locale is the definition of the subset of a user's environment that
depends on language and cultural conventions. It is made up from one or
more categories. Each category is identified by its name and controls
specific aspects of the behavior of components of the system. Category
names correspond to the following environment variable names:
LC_CTYPE Character classification and case conversion.
LC_COLLATE Collation order.
LC_TIME Date and time formats.
LC_NUMERIC Numeric formatting.
LC_MONETARY Monetary formatting.
LC_MESSAGES Formats of informative and diagnostic messages and
interactive responses.
The standard utilities base their behavior on the current locale, as
defined in the ENVIRONMENT VARIABLES section for each utility. The
behavior of some of the C-language functions will also be modified
based on the current locale, as defined by the last call to setlo‐
cale(3C).
Oracle Solaris 11 onwards, locales are enabled or disabled by using
special facets, which are provided by Image Packaging System. For exam‐
ple:
# pkg change-facet locale.ja=true
The above command will enable Japanese locale on the client system. For
more information, see the pkg(7) man page.
Locales other than those supplied by the implementation can be created
by the application by using the localedef(1) utility. The value that is
used to specify a locale when using environment variables will be the
string specified as the name operand to localedef when the locale was
created. The strings "C" and "POSIX" are reserved as identifiers for
the POSIX locale.
Applications can select the desired locale by invoking the setlocale()
function with the appropriate value. If the function is invoked with an
empty string, such as:
setlocale(LC_ALL, "");
the value of the corresponding environment variable is used. If the
environment variable is unset or is set to the empty string, the setlo‐
cale() function sets the appropriate environment.
Locale Definition
Locales can be described with the file format accepted by the localedef
utility.
The locale definition file must contain one or more locale category
source definitions, and must not contain more than one definition for
the same locale category.
A category source definition consists of a category header, a category
body and a category trailer. A category header consists of the charac‐
ter string naming of the category, beginning with the characters LC_.
The category trailer consists of the string END, followed by one or
more blank characters and the string used in the corresponding category
header.
The category body consists of one or more lines of text. Each line con‐
tains an identifier, optionally followed by one or more operands. Iden‐
tifiers are either keywords, identifying a particular locale element,
or collating elements. Each keyword within a locale must have a unique
name (that is, two categories cannot have a commonly-named keyword). No
keyword can start with the characters LC_. Identifiers must be sepa‐
rated from the operands by one or more blank characters.
Operands must be characters, collating elements, or strings of charac‐
ters. Strings must be enclosed in double-quotes ("). Literal double-
quotes within strings must be preceded by the <escape character>, as
described below. When a keyword is followed by more than one operand,
the operands must be separated by semicolons (;). Blank characters are
allowed both before and after a semicolon.
The first category header in the file can be preceded by a line modify‐
ing the comment character. It has the following format, starting in
column 1:
"comment_char %c\n",<comment character>
The comment character defaults to the number sign (#). Blank lines and
lines containing the <comment character> in the first position are
ignored.
The first category header in the file can be preceded by a line modify‐
ing the escape character to be used in the file. It has the following
format, starting in column 1:
"escape_char %c\n",<escape character>
The escape character defaults to backslash.
A line can be continued by placing an escape character as the last
character on the line; this continuation character will be discarded
from the input. Although the implementation need not accept any one
portion of a continued line with a length exceeding {LINE_MAX} bytes,
it places no limits on the accumulated length of the continued line.
Comment lines cannot be continued on a subsequent line using an escaped
newline character.
Individual characters, characters in strings, and collating elements
must be represented using symbolic names, as defined below. In addi‐
tion, characters can be represented using the characters themselves or
as octal, hexadecimal or decimal constants. When non-symbolic notation
is used, the resultant locale definitions will in many cases not be
portable between systems. The left angle bracket (<) is a reserved sym‐
bol, denoting the start of a symbolic name; when used to represent
itself it must be preceded by the escape character. The following rules
apply to character representation:
1. A character can be represented by using a symbolic name,
enclosed within angle brackets < and >. The symbolic name,
including the angle brackets, must exactly match a symbolic
name defined in the charmap file specified by using the
localedef -f option, and will be replaced by a character
value determined from the value associated with the symbolic
name in the charmap file. The use of a symbolic name not
found in the charmap file constitutes an error, unless the
category is LC_CTYPE or LC_COLLATE, in which case it consti‐
tutes a warning condition (see localedef(1) for a descrip‐
tion of action resulting from errors and warnings). The
specification of a symbolic name in a collating-element or
collating-symbol section that duplicates a symbolic name in
the charmap file (if present) is an error. Use of the escape
character or a right angle bracket within a symbolic name is
invalid unless the character is preceded by the escape char‐
acter.
Example:
<C>;<c-cedilla> "<M><a><y>"
2. A character can be represented by the character itself, in
which case the value of the character is implementation-
dependent. Within a string, the double-quote character, the
escape character and the right angle bracket character must
be escaped (preceded by the escape character) to be inter‐
preted as the character itself. Outside strings, the charac‐
ters
, ; < > escape_char
must be escaped to be interpreted as the character itself.
Example:
c "May"
3. A character can be represented as an octal constant. An
octal constant is specified as the escape character followed
by two or more octal digits. Each constant represents a byte
value. Multibyte values can be represented by concatenated
constants specified in byte order with the last constant
specifying the least significant byte of the character.
Example:
\143;\347;\143\150 "\115\141\171"
4. A character can be represented as a hexadecimal constant. A
hexadecimal constant is specified as the escape character
followed by an x followed by two or more hexadecimal digits.
Each constant represents a byte value. Multibyte values can
be represented by concatenated constants specified in byte
order with the last constant specifying the least signifi‐
cant byte of the character.
Example:
\x63;\xe7;\x63\x68 "\x4d\x61\x79"
5. A character can be represented as a decimal constant. A dec‐
imal constant is specified as the escape character followed
by a d followed by two or more decimal digits. Each constant
represents a byte value. Multibyte values can be represented
by concatenated constants specified in byte order with the
last constant specifying the least significant byte of the
character.
Example:
\d99;\d231;\d99\d104 "\d77\d97\d121"
Only characters existing in the character set for which the
locale definition is created can be specified, whether using
symbolic names, the characters themselves, or octal, decimal
or hexadecimal constants. If a charmap file is present, only
characters defined in the charmap can be specified using
octal, decimal or hexadecimal constants. Symbolic names not
present in the charmap file can be specified and will be
ignored, as specified under item 1 above.
LC_CTYPE
The LC_CTYPE category defines character classification, case conversion
and other character attributes. In addition, a series of characters can
be represented by three adjacent periods representing an ellipsis sym‐
bol (...). The ellipsis specification is interpreted as meaning that
all values between the values preceding and following it represent
valid characters. The ellipsis specification is valid only within a
single encoded character set, that is, within a group of characters of
the same size. An ellipsis is interpreted as including in the list all
characters with an encoded value higher than the encoded value of the
character preceding the ellipsis and lower than the encoded value of
the character following the ellipsis.
Example:
\x30;...;\x39;
includes in the character class all characters with encoded values
between the endpoints.
The following keywords are recognized. In the descriptions, the term
automatically included means that it is not an error either to include
or omit any of the referenced characters.
The character classes digit, xdigit, lower, upper, and space have a set
of automatically included characters. These only need to be specified
if the character values (that is, encoding) differ from the implementa‐
tion default values.
upper Define characters to be classified as uppercase let‐
ters.
In the POSIX locale, the 26 uppercase letters are
included:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
In a locale definition file, no character specified
for the keywords cntrl, digit, punct, or space can be
specified. The uppercase letters A to Z are automati‐
cally included in this class.
lower Define characters to be classified as lowercase let‐
ters. In the POSIX locale, the 26 lowercase letters
are included:
a b c d e f g h i j k l m n o p q r s t u v w x y z
In a locale definition file, no character specified
for the keywords cntrl, digit, punct, or space can be
specified. The lowercase letters a to z of the porta‐
ble character set are automatically included in this
class.
alpha Define characters to be classified as letters.
In the POSIX locale, all characters in the classes
upper and lower are included.
In a locale definition file, no character specified
for the keywords cntrl, digit, punct, or space can be
specified. Characters classified as either upper or
lower are automatically included in this class.
digit Define the characters to be classified as numeric
digits.
In the POSIX locale, only
0 1 2 3 4 5 6 7 8 9
are included.
In a locale definition file, only the digits 0, 1, 2,
3, 4, 5, 6, 7, 8, and 9 can be specified, and in con‐
tiguous ascending sequence by numerical value. The
digits 0 to 9 of the portable character set are auto‐
matically included in this class.
The definition of character class digit requires that
only ten characters; the ones defining digits can be
specified; alternative digits (for example, Hindi or
Kanji) cannot be specified here.
alnum Define characters to be classified as letters and
numeric digits. Only the characters specified for the
alpha and digit keywords are specified. Characters
specified for the keywords alpha and digit are auto‐
matically included in this class.
space Define characters to be classified as white-space
characters.
In the POSIX locale, at a minimum, the characters
SPACE, FORMFEED, NEWLINE, CARRIAGE RETURN, TAB, and
VERTICAL TAB are included.
In a locale definition file, no character specified
for the keywords upper, lower, alpha, digit, graph,
or xdigit can be specified. The characters SPACE,
FORMFEED, NEWLINE, CARRIAGE RETURN, TAB, and VERTICAL
TAB of the portable character set, and any characters
included in the class blank are automatically
included in this class.
cntrl Define characters to be classified as control charac‐
ters.
In the POSIX locale, no characters in classes alpha
or print are included.
In a locale definition file, no character specified
for the keywords upper, lower, alpha, digit, punct,
graph, print, or xdigit can be specified.
punct Define characters to be classified as punctuation
characters.
In the POSIX locale, neither the space character nor
any characters in classes alpha, digit, or cntrl are
included.
In a locale definition file, no character specified
for the keywords upper, lower, alpha, digit, cntrl,
xdigit or as the space character can be specified.
graph Define characters to be classified as printable char‐
acters, not including the space character.
In the POSIX locale, all characters in classes alpha,
digit, and punct are included; no characters in class
cntrl are included.
In a locale definition file, characters specified for
the keywords upper, lower, alpha, digit, xdigit, and
punct are automatically included in this class. No
character specified for the keyword cntrl can be
specified.
print Define characters to be classified as printable char‐
acters, including the space character.
In the POSIX locale, all characters in class graph
are included; no characters in class cntrl are
included.
In a locale definition file, characters specified for
the keywords upper, lower, alpha, digit, xdigit,
punct, and the space character are automatically
included in this class. No character specified for
the keyword cntrl can be specified.
xdigit Define the characters to be classified as hexadecimal
digits.
In the POSIX locale, only:
0 1 2 3 4 5 6 7 8 9 A B C D E F a b c d e f
are included.
In a locale definition file, only the characters
defined for the class digit can be specified, in con‐
tiguous ascending sequence by numerical value, fol‐
lowed by one or more sets of six characters repre‐
senting the hexadecimal digits 10 to 15 inclusive,
with each set in ascending order (for example A, B,
C, D, E, F, a, b, c, d, e, f). The digits 0 to 9, the
uppercase letters A to F and the lowercase letters a
to f of the portable character set are automatically
included in this class.
The definition of character class xdigit requires
that the characters included in character class digit
be included here also.
blank Define characters to be classified as blank charac‐
ters.
In the POSIX locale, only the space and tab charac‐
ters are included.
In a locale definition file, the characters space and
tab are automatically included in this class.
charclass Define one or more locale-specific character class
names as strings separated by semicolons. Each named
character class can then be defined subsequently in
the LC_CTYPE definition. A character class name con‐
sists of at least one and at most {CHAR‐
CLASS_NAME_MAX} bytes of alphanumeric characters from
the portable filename character set. The first char‐
acter of a character class name cannot be a digit.
The name cannot match any of the LC_CTYPE keywords
defined in this document.
charclass-name Define characters to be classified as belonging to
the named locale-specific character class. In the
POSIX locale, the locale-specific named character
classes need not exist. If a class name is defined by
a charclass keyword, but no characters are subse‐
quently assigned to it, this is not an error; it rep‐
resents a class without any characters belonging to
it. The charclass-name can be used as the property
argument to the wctype(3C) function, in regular
expression and shell pattern-matching bracket expres‐
sions, and by the tr(1) command.
toupper Define the mapping of lowercase letters to uppercase
letters.
In the POSIX locale, at a minimum, the 26 lowercase
characters:
a b c d e f g h i j k l m n o p q r s t u v w x y z
are mapped to the corresponding 26 uppercase charac‐
ters:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
In a locale definition file, the operand consists of
character pairs, separated by semicolons. The charac‐
ters in each character pair are separated by a comma
and the pair enclosed by parentheses. The first char‐
acter in each pair is the lowercase letter, the sec‐
ond the corresponding uppercase letter. Only charac‐
ters specified for the keywords lower and upper can
be specified. The lowercase letters a to z, and their
corresponding uppercase letters A to Z, of the porta‐
ble character set are automatically included in this
mapping, but only when the toupper keyword is omitted
from the locale definition.
tolower Define the mapping of uppercase letters to lowercase
letters.
In the POSIX locale, at a minimum, the 26 uppercase
characters:
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
are mapped to the corresponding 26 lowercase charac‐
ters:
a b c d e f g h i j k l m n o p q r s t u v w x y z
In a locale definition file, the operand consists of
character pairs, separated by semicolons. The charac‐
ters in each character pair are separated by a comma
and the pair enclosed by parentheses. The first char‐
acter in each pair is the uppercase letter, the sec‐
ond the corresponding lowercase letter. Only charac‐
ters specified for the keywords lower and upper can
be specified. If the tolower keyword is omitted from
the locale definition, the mapping will be the
reverse mapping of the one specified for toupper.
LC_COLLATE
The LC_COLLATE category provides a collation sequence definition for
numerous utilities (such as sort(1), uniq(1), and so forth), regular
expression matching (see regex(7)), and the strcoll(3C), strxfrm(3C),
wcscoll(3C), and wcsxfrm(3C) functions.
A collation sequence definition defines the relative order between col‐
lating elements (characters and multi-character collating elements) in
the locale. This order is expressed in terms of collation values, that
is, by assigning each element one or more collation values (also known
as collation weights). The following capabilities are provided:
1. Multi-character collating elements. Specification of multi-
character collating elements (that is, sequences of two or
more characters to be collated as an entity).
2. User-defined ordering of collating elements. Each collating
element is assigned a collation value defining its order in
the character (or basic) collation sequence. This ordering
is used by regular expressions and pattern matching and,
unless collation weights are explicitly specified, also as
the collation weight to be used in sorting.
3. Multiple weights and equivalence classes. Collating elements
can be assigned one or more (up to the limit
{COLL_WEIGHTS_MAX}) collating weights for use in sorting.
The first weight is hereafter referred to as the primary
weight.
4. One-to-Many mapping. A single character is mapped into a
string of collating elements.
5. Equivalence class definition. Two or more collating elements
have the same collation value (primary weight).
6. Ordering by weights. When two strings are compared to deter‐
mine their relative order, the two strings are first broken
up into a series of collating elements. The elements in each
successive pair of elements are then compared according to
the relative primary weights for the elements. If equal, and
more than one weight has been assigned, the pairs of collat‐
ing elements are recompared according to the relative subse‐
quent weights, until either a pair of collating elements
compare unequal or the weights are exhausted.
The following keywords are recognized in a collation sequence defini‐
tion. They are described in detail in the following sections.
copy Specify the name of an existing locale which is
used as the definition of this category. If this
keyword is specified, no other keyword is speci‐
fied.
point Specify the name of a locale or a relative path‐
name of a locale data file which should be used as
the definition of this category. Unlike the copy
keyword which duplicates the locale category data
for this locale during locale generation, the
point keyword merely yields to save a pointer to
the locale or the locale data file allowing
dynamic locale category data sharing with much
smaller memory requirement. The locale or the
locale data file being pointed to must exist at
the target system for this category to be avail‐
able and usable.
The relative pathname of a locale data file is
identified by one or more slash ('/', 0x2f) char‐
acters in the supplied name. When a relative path‐
name is specified, it is assumed that they are
under the default locale directory shown in the
localedef(1) man page. It is not allowed to have
".." as a directory entry. Leading slash character
is not necessary.
As an example, while:
point "common/my-sorting-order"
will point to /usr/lib/locale/common/my-sorting-
order, the following:
point "en_US.UTF-8"
will point to the category definition of
en_US.UTF-8 locale under the
/usr/lib/locale/en_US.UTF-8/ directory for this
category.
If this keyword is used, no other keyword is spec‐
ified.
Since this keyword is a Solaris-specific exten‐
sion, any portable localedef source files should
not rely on this extension if the source file
portability is important.
collating-element Define a collating-element symbol representing a
multi-character collating element. This keyword is
optional.
collating-symbol Define a collating symbol for use in collation
order statements. This keyword is optional.
order_start Define collation rules. This statement is followed
by one or more collation order statements, assign‐
ing character collation values and collation
weights to collating elements.
order_end Specify the end of the collation-order statements.
collating-element keyword
In addition to the collating elements in the character set, the collat‐
ing-element keyword is used to define multi-character collating ele‐
ments. The syntax is:
"collating-element %s from \"%s\"\n",<collating-symbol>,<string>
The <collating-symbol> operand is a symbolic name, enclosed between
angle brackets (< and >), and must not duplicate any symbolic name in
the current charmap file (if any), or any other symbolic name defined
in this collation definition. The string operand is a string of two or
more characters that collates as an entity. A <collating-element>
defined by using this keyword is only recognized with the LC_COLLATE
category.
Example:
collating-element <ch> from "<c><h>"
collating-element <e-acute> from "<acute><e>"
collating-element <ll> from "ll"
collating-symbol keyword
This keyword will be used to define symbols for use in collation
sequence statements; that is, between the order_start and the order_end
keywords. The syntax is:
"collating-symbol %s\n",<collating-symbol>
The <collating-symbol> is a symbolic name, enclosed between angle
brackets (< and >), and must not duplicate any symbolic name in the
current charmap file (if any), or any other symbolic name defined in
this collation definition.
A collating-symbol defined by using this keyword is only recognized
with the LC_COLLATE category.
Example:
collating-symbol <UPPER_CASE>
collating-symbol <HIGH>
The collating-symbol keyword defines a symbolic name that can be asso‐
ciated with a relative position in the character order sequence. While
such a symbolic name does not represent any collating element, it can
be used as a weight.
order_start keyword
The order_start keyword must precede collation order entries and also
defines the number of weights for this collation sequence definition
and other collation rules.
The syntax of the order_start keyword is:
"order_start %s;%s;...;%s\n",<sort-rules>,<sort-rules>
The operands to the order_start keyword are optional. If present, the
operands define rules to be applied when strings are compared. The num‐
ber of operands define how many weights each element is assigned. If no
operands are present, one forward operand is assumed. If present, the
first operand defines rules to be applied when comparing strings using
the first (primary) weight; the second when comparing strings using the
second weight, and so on. Operands are separated by semicolons (;).
Each operand consists of one or more collation directives, separated by
commas (,). If the number of operands exceeds the {COLL_WEIGHTS_MAX}
limit, the utility will issue a warning message. The following direc‐
tives will be supported:
forward Specifies that comparison operations for the weight level
proceed from start of string toward the end of string.
backward Specifies that comparison operations for the weight level
proceed from end of string toward the beginning of string.
position Specifies that comparison operations for the weight level
will consider the relative position of elements in the
strings not subject to IGNORE. The string containing an
element not subject to IGNORE after the fewest collating
elements subject to IGNORE from the start of the compare
will collate first. If both strings contain a character not
subject to IGNORE in the same relative position, the col‐
lating values assigned to the elements will determine the
ordering. In case of equality, subsequent characters not
subject to IGNORE are considered in the same manner.
The directives forward and backward are mutually exclusive.
Example:
order_start forward;backward
If no operands are specified, a single forward operand is assumed.
Collation Order
The order_start keyword is followed by collating identifier entries.
The syntax for the collating element entries is:
"%s %s;%s;...;%s\n"<collating-identifier>,<weight>,<weight>,...
Each collating-identifier consists of either a character described in
Locale Definition above, a <collating-element>, a <collating-symbol>,
an ellipsis, or the special symbol UNDEFINED. The order in which col‐
lating elements are specified determines the character order sequence,
such that each collating element compares less than the elements fol‐
lowing it. The NUL character compares lower than any other character.
A <collating-element> is used to specify multi-character collating ele‐
ments, and indicates that the character sequence specified by using the
<collating-element> is to be collated as a unit and in the relative
order specified by its place.
A <collating-symbol> is used to define a position in the relative order
for use in weights. No weights are specified with a <collating-symbol>.
The ellipsis symbol specifies that a sequence of characters will col‐
late according to their encoded character values. It is interpreted as
indicating that all characters with a coded character set value higher
than the value of the character in the preceding line, and lower than
the coded character set value for the character in the following line,
in the current coded character set, will be placed in the character
collation order between the previous and the following character in
ascending order according to their coded character set values. An ini‐
tial ellipsis is interpreted as if the preceding line specified the NUL
character, and a trailing ellipsis as if the following line specified
the highest coded character set value in the current coded character
set. An ellipsis is treated as invalid if the preceding or following
lines do not specify characters in the current coded character set. The
use of the ellipsis symbol ties the definition to a specific coded
character set and may preclude the definition from being portable
between implementations.
The symbol UNDEFINED is interpreted as including all coded character
set values not specified explicitly or by using the ellipsis symbol.
Such characters are inserted in the character collation order at the
point indicated by the symbol, and in ascending order according to
their coded character set values. If no UNDEFINED symbol is specified,
and the current coded character set contains characters not specified
in this section, the utility will issue a warning message and place
such characters at the end of the character collation order.
The optional operands for each collation-element are used to define the
primary, secondary, or subsequent weights for the collating element.
The first operand specifies the relative primary weight, the second the
relative secondary weight, and so on. Two or more collation-elements
can be assigned the same weight; they belong to the same equivalence
class if they have the same primary weight. Collation behaves as if,
for each weight level, elements subject to IGNORE are removed, unless
the position collation directive is specified for the corresponding
level with the order_start keyword. Then each successive pair of ele‐
ments is compared according to the relative weights for the elements.
If the two strings compare equal, the process is repeated for the next
weight level, up to the limit {COLL_WEIGHTS_MAX}.
Weights are expressed as characters described in Locale Definition
above, <collating-symbol>s, <collating-element>s, an ellipsis, or the
special symbol IGNORE. A single character, a <collating-symbol> or a
<collating-element> represent the relative position in the character
collating sequence of the character or symbol, rather than the charac‐
ter or characters themselves. Thus, rather than assigning absolute val‐
ues to weights, a particular weight is expressed using the relative
order value assigned to a collating element based on its order in the
character collation sequence.
One-to-many mapping is indicated by specifying two or more concatenated
characters or symbolic names. For example, if the character <eszet> is
given the string "<s><s>" as a weight, comparisons are performed as if
all occurrences of the character <eszet> are replaced by <s><s> (assum‐
ing that <s> has the collating weight <s>). If it is necessary to
define <eszet> and <s><s> as an equivalence class, then a collating
element must be defined for the string ss.
All characters specified by using an ellipsis will by default be
assigned unique weights, equal to the relative order of characters.
Characters specified by using an explicit or implicit UNDEFINED special
symbol will by default be assigned the same primary weight (that is,
belong to the same equivalence class). An ellipsis symbol as a weight
is interpreted to mean that each character in the sequence has unique
weights, equal to the relative order of their character in the charac‐
ter collation sequence. The use of the ellipsis as a weight is treated
as an error if the collating element is neither an ellipsis nor the
special symbol UNDEFINED.
The special keyword IGNORE as a weight indicates that when strings are
compared using the weights at the level where IGNORE is specified, the
collating element is ignored; that is, as if the string did not contain
the collating element. In regular expressions and pattern matching, all
characters that are subject to IGNORE in their primary weight form an
equivalence class.
An empty operand is interpreted as the collating element itself.
For example, the order statement:
<a> <a>;<a>
is equal to:
<a>
An ellipsis can be used as an operand if the collating element was an
ellipsis, and is interpreted as the value of each character defined by
the ellipsis.
The collation order as defined in this section defines the interpreta‐
tion of bracket expressions in regular expressions.
Example:
tab(); lw(2.75i) lw(2.75i) order_startforward;backward UNDEFINEDIG‐
NORE;IGNORE <LOW> <space><LOW>;<space> ...<LOW>;... <a><a>;<a> <a-
acute><a>;<a-acute> <a-grave><a>;<a-grave> <A><a>;<A> <A-acute><a>;<A-
acute> <A-grave><a>;<A-grave> <ch><ch>;<ch> <Ch><ch>;<Ch> <s><s>;<s>
<eszet>"<s><s>";"<eszet><eszet>" order_end
This example is interpreted as follows:
1. The UNDEFINED means that all characters not specified in
this definition (explicitly or by using the ellipsis) are
ignored for collation purposes; for regular expression pur‐
poses they are ordered first.
2. All characters between <space> and <a> have the same primary
equivalence class and individual secondary weights based on
their ordinal encoded values.
3. All characters based on the upper- or lower-case character a
belong to the same primary equivalence class.
4. The multi-character collating element <ch> is represented by
the collating symbol <ch> and belongs to the same primary
equivalence class as the multi-character collating element
<Ch>.
order_end keyword
The collating order entries must be terminated with an order_end key‐
word.
LC_MONETARY
The LC_MONETARY category defines the rules and symbols that are used to
format monetary numeric information. This information is available
through the localeconv(3C) function.
The following items are defined in this category of the locale. The
item names are the keywords recognized by the localedef(1) utility when
defining a locale. They are also similar to the member names of the
lconv structure defined in <locale.h>. The localeconv function returns
{CHAR_MAX} for unspecified integer items and the empty string ("") for
unspecified or size zero string items.
In a locale definition file the operands are strings. For some key‐
words, the strings can contain only integers. Keywords that are not
provided, string values set to the empty string (""), or integer key‐
words set to −1, are used to indicate that the value is not available
in the locale.
int_curr_symbol The international currency symbol. The operand is
a four-character string, with the first three
characters containing the alphabetic interna‐
tional currency symbol in accordance with those
specified in the ISO 4217 standard. The fourth
character is the character used to separate the
international currency symbol from the monetary
quantity.
currency_symbol The string used as the local currency symbol.
mon_decimal_point The operand is a string containing the symbol
that is used as the decimal delimiter (radix
character) in monetary formatted quantities.
mon_thousands_sep The operand is a string containing the symbol
that is used as a separator for groups of digits
to the left of the decimal delimiter in formatted
monetary quantities.
mon_grouping Define the size of each group of digits in for‐
matted monetary quantities. The operand is a
sequence of integers separated by semicolons.
Each integer specifies the number of digits in
each group, with the initial integer defining the
size of the group immediately preceding the deci‐
mal delimiter, and the following integers defin‐
ing the preceding groups. If the last integer is
not −1, then the size of the previous group (if
any) will be repeatedly used for the remainder of
the digits. If the last integer is −1, then no
further grouping will be performed.
The following is an example of the interpretation
of the mon_grouping keyword. Assuming that the
value to be formatted is 123456789 and the
mon_thousands_sep is ', then the following table
shows the result. The third column shows the
equivalent string in the ISO C standard that
would be used by the localeconv function to
accommodate this grouping.
mon_grouping Formatted Value ISO C String
3;-1 123456'789 "\3\177"
3 123'456'789 "\3"
3;2;-1 1234'56'789 "\3\2\177"
3;2 12'34'56'789 "\3\2"
-1 1234567898 "\177"
In these examples, the octal value of {CHAR_MAX}
is 177.

formatted monetary quantity.
negative_sign A string used to indicate a negative-valued for‐
matted monetary quantity.

digits (those to the right of the decimal delim‐
iter) to be written in a formatted monetary quan‐
tity using int_curr_symbol.

The entry n/a indicates that the value is not available in the POSIX
locale.
LC_NUMERIC
The LC_NUMERIC category defines the rules and symbols that will be used
to format non-monetary numeric information. This information is avail‐
able through the localeconv(3C) function.
The following items are defined in this category of the locale. The
item names are the keywords recognized by the localedef utility when
defining a locale. They are also similar to the member names of the
lconv structure defined in <locale.h>. The localeconv() function
returns {CHAR_MAX} for unspecified integer items and the empty string
("") for unspecified or size zero string items.
In a locale definition file the operands are strings. For some key‐
words, the strings only can contain integers. Keywords that are not
provided, string values set to the empty string (""), or integer key‐
words set to −1, will be used to indicate that the value is not avail‐
able in the locale. The following keywords are recognized:
decimal_point The operand is a string containing the symbol that is
used as the decimal delimiter (radix character) in
numeric, non-monetary formatted quantities. This key‐
word cannot be omitted and cannot be set to the empty
string. In contexts where standards limit the deci‐
mal_point to a single byte, the result of specifying a
multibyte operand is unspecified.
thousands_sep The operand is a string containing the symbol that is
used as a separator for groups of digits to the left
of the decimal delimiter in numeric, non-monetary for‐
matted monetary quantities. In contexts where stan‐
dards limit the thousands_sep to a single byte, the
result of specifying a multibyte operand is unspeci‐
fied.
grouping Define the size of each group of digits in formatted
non-monetary quantities. The operand is a sequence of
integers separated by semicolons. Each integer speci‐
fies the number of digits in each group, with the ini‐
tial integer defining the size of the group immedi‐
ately preceding the decimal delimiter, and the follow‐
ing integers defining the preceding groups. If the
last integer is not −1, then the size of the previous
group (if any) will be repeatedly used for the remain‐
der of the digits. If the last integer is −1, then no
further grouping will be performed. The non-monetary
numeric formatting definitions for the POSIX locale
follow. The code listing depicts the localedef input,
the table representing the same information with the
addition of localeconv values, and nl_langinfo con‐
stants.

LC_TIME
The LC_TIME category defines the interpretation of the field descrip‐
tors supported by date(1) and affects the behavior of the strftime(3C),
wcsftime(3C), strptime(3C), and nl_langinfo(3C) functions. Because the
interfaces for C-language access and locale definition differ signifi‐
cantly, they are described separately. For locale definition, the fol‐
lowing mandatory keywords are recognized:
abday Define the abbreviated weekday names, corresponding to
the %a field descriptor (conversion specification in the
strftime(), wcsftime(), and strptime() functions). The
operand consists of seven semicolon-separated strings,
each surrounded by double-quotes. The first string is
the abbreviated name of the day corresponding to Sunday,
the second the abbreviated name of the day corresponding
to Monday, and so on.
day Define the full weekday names, corresponding to the %A
field descriptor. The operand consists of seven semi‐
colon-separated strings, each surrounded by double-
quotes. The first string is the full name of the day
corresponding to Sunday, the second the full name of the
day corresponding to Monday, and so on.
abmon Define the abbreviated month names, corresponding to the
%b field descriptor. The operand consists of twelve
semicolon-separated strings, each surrounded by double-
quotes. The first string is the abbreviated name of the
first month of the year (January), the second the abbre‐
viated name of the second month, and so on.
mon Define the full month names, corresponding to the %B
field descriptor. The operand consists of twelve semi‐
colon-separated strings, each surrounded by double-
quotes. The first string is the full name of the first
month of the year (January), the second the full name of
the second month, and so on.
d_t_fmt Define the appropriate date and time representation,
corresponding to the %c field descriptor. The operand
consists of a string, and can contain any combination of
characters and field descriptors. In addition, the
string can contain the escape sequences \\, \a, \b, \f,
\n, \r, \t, \v.
date_fmt Define the appropriate date and time representation,
corresponding to the %C field descriptor. The operand
consists of a string, and can contain any combination of
characters and field descriptors. In addition, the
string can contain the escape sequences \\, \a, \b, \f,
\n, \r, \t, \v.
d_fmt Define the appropriate date representation, correspond‐
ing to the %x field descriptor. The operand consists of
a string, and can contain any combination of characters
and field descriptors. In addition, the string can con‐
tain the escape sequences \\, \a, \b, \f, \n, \r, \t,
\v.
t_fmt Define the appropriate time representation, correspond‐
ing to the %X field descriptor. The operand consists of
a string, and can contain any combination of characters
and field descriptors. In addition, the string can con‐
tain the escape sequences \\, \a, \b, \f, \n, \r, \t,
\v.
am_pm Define the appropriate representation of the ante meri‐
diem and post meridiem strings, corresponding to the %p
field descriptor. The operand consists of two strings,
separated by a semicolon, each surrounded by double-
quotes. The first string represents the ante meridiem
designation, the last string the post meridiem designa‐
tion.
t_fmt_ampm Define the appropriate time representation in the
12-hour clock format with am_pm, corresponding to the %r
field descriptor. The operand consists of a string and
can contain any combination of characters and field
descriptors. If the string is empty, the 12-hour format
is not supported in the locale.
era Define how years are counted and displayed for each era
in a locale. The operand consists of semicolon-separated
strings. Each string is an era description segment with
the format:
direction:offset:start_date:end_date:era_name:era_format
according to the definitions below. There can be as many
era description segments as are necessary to describe
the different eras.
The start of an era might not be the earliest point For
example, the Christian era B.C. starts on the day before
January 1, A.D. 1, and increases with earlier time.
direction Either a + or a − character. The + charac‐
ter indicates that years closer to the
start_date have lower numbers than those
closer to the end_date. The − character
indicates that years closer to the
start_date have higher numbers than those
closer to the end_date.
offset The number of the year closest to the
start_date in the era, corresponding to
the %Eg and %Ey field descriptors.
start_date A date in the form yyyy/mm/dd, where yyyy,
mm, and dd are the year, month and day
numbers respectively of the start of the
era. Years prior to A.D. 1 are represented
as negative numbers.
end_date The ending date of the era, in the same
format as the start_date, or one of the
two special values −* or +*. The value −*
indicates that the ending date is the
beginning of time. The value +* indicates
that the ending date is the end of time.
era_name A string representing the name of the era,
corresponding to the %EC field descriptor.
era_format A string for formatting the year in the
era, corresponding to the %EG and %EY
field descriptors.
era_d_fmt Define the format of the date in alternative era nota‐
tion, corresponding to the %Ex field descriptor.
era_t_fmt Define the locale's appropriate alternative time format,
corresponding to the %EX field descriptor.
era_d_t_fmt Define the locale's appropriate alternative date and
time format, corresponding to the %Ec field descriptor.
alt_digits Define alternative symbols for digits, corresponding to
the %O field descriptor modifier. The operand consists
of semicolon-separated strings, each surrounded by dou‐
ble-quotes. The first string is the alternative symbol
corresponding with zero, the second string the symbol
corresponding with one, and so on. Up to 100 alternative
symbol strings can be specified. The %O modifier indi‐
cates that the string corresponding to the value speci‐
fied by using the field descriptor will be used instead
of the value.
LC_TIME C-language Access
The following information can be accessed. These correspond to con‐
stants defined in <langinfo.h> and used as arguments to the nl_lang‐
info(3C) function.
ABDAY_x The abbreviated weekday names (for example Sun), where x
is a number from 1 to 7.

are counted and displayed for each era in a locale. Each
era description segment has the format:
direction:offset:start_date:end_date:era_name:era_format
according to the definitions below. There will be as
many era description segments as are necessary to
describe the different eras. Era description segments
are separated by semicolons.
The start of an era might not be the earliest point For
example, the Christian era B.C. starts on the day before
January 1, A.D. 1, and increases with earlier time.
direction Either a + or a − character. The + charac‐
ter indicates that years closer to the
start_date have lower numbers than those
closer to the end_date. The − character
indicates that years closer to the
start_date have higher numbers than those
closer to the end_date.
offset The number of the year closest to the
start_date in the era.
start_date A date in the form yyyy/mm/dd, where yyyy,
mm, and dd are the year, month and day
numbers respectively of the start of the
era. Years prior to AD 1 are represented
as negative numbers.
end_date The ending date of the era, in the same
format as the start_date, or one of the
two special values, −* or +*. The value −*
indicates that the ending date is the
beginning of time. The value +* indicates
that the ending date is the end of time.

%O conversion specification modifier. The value consists
of semicolon-separated symbols. The first is the alter‐
native symbol corresponding to zero, the second is the
symbol corresponding to one, and so on. Up to 100 alter‐
native symbols may be specified. The following table
displays the correspondence between the items described
above and the conversion specifiers used by date(1) and
the strftime(3C), wcsftime(3C), and strptime(3C) func‐

LC_TIME General Information
Although certain of the field descriptors in the POSIX locale (such as
the name of the month) are shown with initial capital letters, this
need not be the case in other locales. Programs using these fields may
need to adjust the capitalization if the output is going to be used at
the beginning of a sentence.
The LC_TIME descriptions of abday, day, mon, and abmon imply a Grego‐
rian style calendar (7-day weeks, 12-month years, leap years, and so
forth). Formatting time strings for other types of calendars is outside
the scope of this document set.
As specified under date in Locale Definition and strftime(3C), the
field descriptors corresponding to the optional keywords consist of a
modifier followed by a traditional field descriptor (for instance %Ex).
If the optional keywords are not supported by the implementation or are
unspecified for the current locale, these field descriptors are treated
as the traditional field descriptor. For instance, assume the following
keywords:
alt_digits "0th" ; "1st" ; "2nd" ; "3rd" ; "4th" ; "5th" ; \
"6th" ; "7th" ; "8th" ; "9th" ; "10th">
d_fmt "The %Od day of %B in %Y"
On 7/4/1776, the %x field descriptor would result in "The 4th day of
July in 1776" while 7/14/1789 would come out as "The 14 day of July in
1789" The above example is for illustrative purposes only. The %O modi‐
fier is primarily intended to provide for Kanji or Hindi digits in date
formats.
LC_MESSAGES
The LC_MESSAGES category defines the format and values for affirmative
and negative responses.
The following keywords are recognized as part of the locale definition
file. The nl_langinfo(3C) function accepts uppercase versions of the
first four keywords.
yesexpr The operand consists of an extended regular expression (see
regex(7)) that describes the acceptable affirmative response
to a question expecting an affirmative or negative response.
noexpr The operand consists of an extended regular expression that
describes the acceptable negative response to a question
expecting an affirmative or negative response.
yesstr The operand consists of a fixed string (not a regular
expression) that can be used by an application for composi‐
tion of a message that lists an acceptable affirmative
response, such as in a prompt.
nostr The operand consists of a fixed string that can be used by
an application for composition of a message that lists an
acceptable negative response. The format and values for
affirmative and negative responses of the POSIX locale fol‐
