6 charmap - character set description file
7
9 A character set description (charmap) defines all available characters
10 and their encodings in a character set. localedef(1) can use charmaps
11 to create locale variants for different character sets.
12
13 Syntax
14 The charmap file starts with a header that may consist of the following
15 keywords:
16
17 <code_set_name>
18 is followed by the name of the character map.
19
20 <comment_char>
21 is followed by a character that will be used as the comment
22 character for the rest of the file. It defaults to the number
23 sign (#).
24
25 <escape_char>
26 is followed by a character that should be used as the escape
27 character for the rest of the file to mark characters that
28 should be interpreted in a special way. It defaults to the
29 backslash (\).
30
31 <mb_cur_max>
32 is followed by the maximum number of bytes for a character. The
33 default value is 1.
34
35 <mb_cur_min>
36 is followed by the minimum number of bytes for a character.
37 This value must be less than or equal than <mb_cur_max>. If not
38 specified, it defaults to <mb_cur_max>.
39
40 The character set definition section starts with the keyword CHARMAP in
41 the first column.
42
43 The following lines may have one of the two following forms to define
44 the character set:
45
46 <character> byte-sequence comment
47 This form defines exactly one character and its byte sequence,
48 comment being optional.
49
50 <character>..<character> byte-sequence comment
51 This form defines a character range and its byte sequence, com‐
52 ment being optional.
53
54 The character set definition section ends with the string END CHARMAP.
55
56 The character set definition section may optionally be followed by a
57 section to define widths of characters.
58
59 The WIDTH_DEFAULT keyword can be used to define the default width for
60 all characters not explicitly listed. The default character width is
61 1.
62
63 The width section for individual characters starts with the keyword
64 WIDTH in the first column.
65
66 The following lines may have one of the two following forms to define
67 the widths of the characters:
68
69 <character> width
70 This form defines the width of exactly one character.
71
72 <character>...<character> width
73 This form defines the width for all the characters in the range.
74
75 The width definition section ends with the string END WIDTH.
76
78 /usr/share/i18n/charmaps
79 Usual default character map path.
80
82 POSIX.2.
83
85 The Euro sign is defined as follows in the UTF-8 charmap:
86
87 <U20AC> /xe2/x82/xac EURO SIGN
88
90 iconv(1), locale(1), localedef(1), locale(5), charsets(7)
