Notes on CJK Character Codes and Encodings
The character codes covered are:
- Big-5
-
A code for traditional Chinese,
widely used in Hong Kong, Taiwan and elsewhere.
- 94x94 Character Sets
-
These codes represent each character by a pair of numbers 1-94 (decimal),
called row and column respectively
("kuten" in Japanese, "qu1wei4" in Chinese).
The idea is to map onto the 94 graphic ASCII bytes,
by adding 0x20 to each (0xA0 for shifted ASCII).
- CCCII and ANSI Z39.64-1989 (EACC)
-
Two closely related 3-byte codes, intended to cover all CJK languages.
- Unicode/ISO-10646
-
A new code covering most of the world's languages.
- International Standard--Information Processing-- ISO 7-bit and 8-bit
coded character sets--Code extension techniques, ISO 2022:1986.
(= ANSI X3.41, JIS X0202, BS 6856, FIPS 35, ECMA 35)
