NAME
charmap - character set description file
DESCRIPTION
A character set description (charmap) defines all available characters and their encodings in a character set. localedef(1) can use charmaps to create locale variants for different character sets.
Syntax
The charmap file starts with a header that may consist of the following keywords:
The width definition section ends with the string END WIDTH.
| <code_set_name> | |
| is followed by the name of the character map. | |
| <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 (#). | |
| <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 (\). | |
| <mb_cur_max> | |
| is followed by the maximum number of bytes for a character. The default value is 1. | |
| <mb_cur_min> | |
| is followed by the minimum number of bytes for a character. This value must be less than or equal than <mb_cur_max>. If not specified, it defaults to <mb_cur_max>. | |
| The character set definition section starts with the keyword CHARMAP in the first column. | |
| The following lines may have one of the two following forms to define the character set: | |
| <character> byte-sequence comment | |
| This form defines exactly one character and its byte sequence, comment being optional. | |
| <character>..<character> byte-sequence comment | |
| This form defines a character range and its byte sequence, comment being optional. | |
| The character set definition section ends with the string END CHARMAP. | |
| The character set definition section may optionally be followed by a section to define widths of characters. | |
| The WIDTH_DEFAULT keyword can be used to define the default width for all characters not explicitly listed. The default character width is 1. | |
| The width section for individual characters starts with the keyword WIDTH in the first column. | |
| The following lines may have one of the two following forms to define the widths of the characters: | |
| <character> width | |
| This form defines the width of exactly one character. | |
| <character>...<character> width | |
| This form defines the width for all the characters in the range. | |
