  22 (1) Format of mapping files
  23
  24 Each line contains a code point and the corresponding Unicode
  25 character code separated by a space.  Both code points and Unicode
  26 character codes are in hexadecimal preceded by "0x".  Comments may be
  27 used, starting with "#".  Code ranges may also be used, with
  28 (inclusive) start and end code points separated by "-" followed by the
  29 Unicode of the start of the range
  30
  31 Examples:
  32 0xA0 0x00A0  # no-break space
  33
  34 0x8141-0x8143 0x4E04 # map onto a Unicode range

  37 (2) Source of mapping files
  38
  39 All mapping files are generated automatically from data files freely
  40 available on the Internet (e.g. glibc/localedata/charmaps").  See the
  41 file ../../admin/charsets/mapfiles/README for the detail.
