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 for 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
mutlibyte-characters, which are currently not implemented.
The last line in a charmap-definition file must contain
END CHARMAP.
