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  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

   POSIX.2.

EXAMPLE

   The Euro sign is defined as follows in the UTF-8 charmap:

   <U20AC>     /xe2/x82/xac EURO SIGN
