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).
