charmap - character symbols to define character encodings
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.
The charmap file starts with a header, that may consist of the

The charmap-definition itself starts with the keyword

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 useful only for
multibyte-characters, which are currently not implemented.
The last line in a charmap-definition file must contain
