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 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.

FILES

       /usr/share/i18n/charmaps
              Usual default character map path.

CONFORMING TO

       <U20AC>     /xe2/x82/xac EURO SIGN
