charmap - character symbols to define character encodings
A character set description (charmap) defines a character set of avail
able 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 follow

is followed by the max number of bytes for a multibyte-charac
ter. Multibyte characters are currently not supported. The
default value is 1.
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.
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 ( \ ).
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
The following lines may have one of the two following forms to define
This form defines exactly one character and its encoding.
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.
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 are interpreted as
itself; for example, the sequence <\\\>> represents the symbolic name
\> enclosed in angle brackets.
The encoding may be in each of the following three forms:
with a decimal number
with a hexadecimal number
with an octal number.
