GBK(5)
NAME
GBK, gbk - A character encoding system (codeset) for Simplified Chinese
DESCRIPTION
The GBK character set is an extension to the GB 2312-80 character set. (The
"K" in "GBK" is the first sound in the Chinese word "Kuo Zhan," which means
"extension.") GBK includes all the Hanzi characters specified by the ISO
10646-1:1993 standard (characters also known as the GB 13000.1.93 character
set) that are not included in GB 2312-80. GBK is therefore defined as a
normative annex of GB13000.1-93.
GBK Value Ranges and Code Points
The GBK codeset is divided into five levels, as follows:
___________________________________________________________
Level Encoding Range Code Points
Characters
___________________________________________________________
GBK/1 0xA1A1-0xA9FE 846 717
GBK/2 0xB0A1-0xF7FE 6,768 6,763
GBK/3 0x8140-0xA0FE 6,080 6,080
GBK/4 0xAA40-0xFE40 8,160 8,160
GBK/5 0xA840-0xA9A0 192 166
___________________________________________________________
In addition, GBK includes code points for user-defined characters, as
follows:
____________________________
Encoding Range Code Points
____________________________
0xAAA1-0xAFFE 564
0xF8A1-0xFEFE 658
0xA140-0xA7A0 672
____________________________
GBK therefore provides a total of 23,940 code points, 21,886 of which are
assigned.
Each row in the GBK code table consists of 190 characters. ASCII
characters, which are single-byte characters, are defined in the range
0x21-0x7E. Encoding ranges for two-byte characters are as follows:
Encoding range for the first byte: 0x81-0xFE
Encoding ranges for the second byte: 0x40-0x7E and 0x80-0xFE
Note
In terms of character-to-code allocation, the sub-range for GB2321-80
characters (0xA1A1-0xFEFE) in GBK is the same encoding range defined
for these characters in Extended UNIX Code (EUC). GBK is therefore
backward compatible with Chinese EUC encoding as well as forward
compatible with the encoding as defined by ISO 10646-1:1993.
GBK is the standard character set and encoding used in the Simplified
Chinese version of Windows 95.

These fonts can be used for printing only with Chinese text printers. The
SongTi fonts are the default screen fonts for the GBK codeset.
