23 (1) Format of mapping files
25 Each line contains a code point and the corresponding Unicode
26 character code separated by a space. Both code points and Unicode
27 character codes are in hexadecimal preceded by "0x". Comments may be
28 used, starting with "#". Code ranges may also be used, with
29 (inclusive) start and end code points separated by "-" followed by the
30 Unicode of the start of the range
33 0xA0 0x00A0 # no-break space
35 0x8141-0x8143 0x4E04 # map onto a Unicode range
38 (2) Source of mapping files
40 All mapping files are generated automatically from data files freely
41 available on the Internet (e.g. glibc/localedata/charmaps"). See the
42 file ../../admin/charsets/mapfiles/README for the detail.
