CHARMAP(5) Linux Programmer's Manual CHARMAP(5)
NAME
charmap - character set description file
DESCRIPTION
A character set description (charmap) defines all available characters and their encodings
in a character set. localedef(1) can use charmaps to create locale variants for different
character sets.
Syntax
The charmap file starts with a header that may consist of the following keywords:
<code_set_name>
is followed by the name of the character map.
<comment_char>
is followed by a character that will be used as the comment character for the rest
of the file. It defaults to the number sign (#).
<escape_char>
is followed by a character that should be used as the escape character for the rest
of the file to mark characters that should be interpreted in a special way. It de-
faults to the backslash (\).
<mb_cur_max>
is followed by the maximum number of bytes for a character. The default value is
1.
<mb_cur_min>
is followed by the minimum number of bytes for a character. This value must be
less than or equal than <mb_cur_max>. If not specified, it defaults to
<mb_cur_max>.
The character set definition section starts with the keyword CHARMAP in the first column.
The following lines may have one of the two following forms to define the character set:
<character> byte-sequence comment
This form defines exactly one character and its byte sequence, comment being op-
tional.
<character>..<character> byte-sequence comment
This form defines a character range and its byte sequence, comment being optional.
The character set definition section ends with the string END CHARMAP.
The character set definition section may optionally be followed by a section to define
widths of characters.
The WIDTH_DEFAULT keyword can be used to define the default width for all characters not
explicitly listed. The default character width is 1.
The width section for individual characters starts with the keyword WIDTH in the first
column.
The following lines may have one of the two following forms to define the widths of the
characters:
<character> width
This form defines the width of exactly one character.
<character>...<character> width
This form defines the width for all the characters in the range.
The width definition section ends with the string END WIDTH.
