CHARMAP(5)              Linux Programmer's Manual             CHARMAP(5)

NAME         top

       charmap - character set description file

DESCRIPTION         top

       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 defaults 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 optional.

       <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.
