charmap - character symbols to define character encodings
A character set description (charmap) defines a characterset 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 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 mutlibyte-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
<escape_char> 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:
- <escape_char>d<number>
- with a decimal number
- <escape_char>x<number>
- with a hexadecimal number
- <escape_char><number>
- with an octal number.
