charmap
NAME
charmap - character symbols to define character encodings
DESCRIPTION
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 portable character set is defined in the
file
/.us/.li/nls/charmap/POSIX
for reference purposes.
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 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.
SYMBOLIC NAMES
A
symbolic name
for a character contains only characters of the
portable character set.
The name itself isenclosed between angle brackets.
Characters following the
<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.
