3.3.4: BIG FIVE

    Big Five is the encoding system used on machines that support
MS-DOS or Windows, and also for Macintosh (such as the Chinese
Language Kit or the fully-localized operating system).

  Two-byte Standard Characters                  Encoding Ranges
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^                  ^^^^^^^^^^^^^^^
  first byte range                              0xA1-0xFE
  second byte ranges                            0x40-0x7E, 0xA1-0xFE

  One-byte Characters                           Encoding Range
  ^^^^^^^^^^^^^^^^^^^                           ^^^^^^^^^^^^^^
  ASCII                                         0x21-0x7E

    The encoding used on Macintosh is quite similar to the above,
but has a slightly shortened two-byte range (second byte range up to
0xFC only) plus additional one-byte code points, namely 0x80
(backslash), 0xFD ("copyright" symbol: "c" in a circle), 0xFE
("trademark" symbol: "TM" as a superscript), and 0xFF ("ellipsis"
symbol: three dots).
