  26 (1) Format of mapping files
  27
  28 Each line contains a code point and the corresponding Unicode
  29 character code separated by a space.  Both code points and Unicode
  30 character codes are in hexadecimal preceded by "0x".  Comments may be
  31 used, starting with "#".  Code ranges may also be used, with
  32 (inclusive) start and end code points separated by "-" followed by the
  33 unicode of the start of the range
  34
  35 Examples:
  36 0xA0 0x00A0  # no-break space
  37
  38 0x8141-0x8143 0x4E04 # map onto a Unicode range

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