Chapter 3: Character Set Standards

Chinese Character Set Standards—Singapore

Singapore ( xīnjiāpō) does not have its own character set standard, and simply

uses China’s GB 2312-80 as its character set. However, 226 of the 6,582 ideographs in CJK

Unied Ideographs Extension A, introduced in Unicode version 3.0, map to a Singapore

source. e source is not named and is simply referred to as Singapore characters. To what

extent these 226 characters are ad-hoc, or codied by a Singapore national standard, is

unknown, at least to me. My suspicion is that they are ad-hoc simply for the apparent lack

of any Singapore national standard.

Japanese Character Set Standards

Six CCSes are widely used in Japan. ese character sets are ASCII, JIS-Roman, half-width

katakana, JIS X 0208:1997 (and its predecessors), JIS X 0212-1990, and JIS X 0213:2004.

ASCII and JIS-Roman were already discussed. JIS-Roman and half-width katakana

*

are

described in JIS X 0201-1997. e most common of these CCSes is JIS X 0208:1997,

which includes JIS Levels 1 and 2. e sixth standard, JIS X 0213:2004, denes JIS Levels

3 and 4.

is section includes a description of the latest character set standards established by

Japan. e two most common Japanese character set standards are JIS X 0208:1997 and

JIS X 0213:2004. JIS X 0221:2007, which is directly aligned with and equivalent to ISO

10646:2003 ...
