• NAME
  
  charmap - character symbols to define character encodings
• DESCRIPTION
  
  A character set description (charmap) defines a character set of available characters and their encodings. All supported character sets should have the portable character set as a proper subset. Syntax The charmap file starts with a header, that may consist of the following keywords:

  <codeset>

  is followed by the name of the codeset.

  <mb_cur_max>

  is followed by the max number of bytes for a multibyte-character. Multibyte characters are currently not supported. The default value is 1.

  <mb_cur_min>

  is followed by the min number of bytes for a character. This value must be less or equal than mb_cur_max . If not specified, it defaults to mb_cur_max .

  <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 ( \\ ).

  <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 ( # ).
  
  The charmap-definition itself starts with the keyword CHARMAP in column 1.
  The following lines may have one of the two following forms to define the character-encodings:

  <symbolic-name> <encoding> <comments>

  This form defines exactly one character and its encoding.

  <symbolic-name>...<symbolic-name> <encoding> <comments>

  This form defines a couple of characters. This is only useful for multibyte-characters, which are currently not implemented.
  
  The last line in a charmap-definition file must contain END CHARMAP. "Symbolic Names" A symbolic name for a character contains only characters of the portable character set. The name itself is enclosed between angle brackets. Characters following an <escape_char> are interpreted as itself; for example, the sequence <\\\\\\\\\\\\>> represents the symbolic name \\\\> enclosed in angle brackets. "Character Encoding" The encoding may be in each of the following three forms:

  <escape_char>d<number>

  with a decimal number

  <escape_char>x<number>

  with a hexadecimal number

  <escape_char><number>

  with an octal number.
