  25 (1) Format of mapping files
  26
  27 Each line contains a code point and the corresponding Unicode
  28 character code separated by a space.  Both code points and Unicode
  29 character codes are in hexadecimal preceded by "0x".  Comments may be
  30 used, starting with "#".  Code ranges may also be used, with
  31 (inclusive) start and end code points separated by "-" followed by the
  32 unicode of the start of the range
  33
  34 Examples:
  35 0xA0 0x00A0  # no-break space
  36
  37 0x8141-0x8143 0x4E04 # map onto a Unicode range

  40 (2) Source of mapping files
  41
  42 All mapping files are generated automatically from data files freely
  43 available on the Internet (e.g. glibc/localedata/charmaps").  See the
  44 file ../../admin/charsets/Makefile for the detail.
