Name
charmap — character symbols to define character
encodings
DESCRIPTION
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.
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 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.
SYMBOLIC NAMES
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.
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.
