GB 12345

Source: Wikipedia, the free encyclopedia.

GB 12345,

character set standard established by China, and can be thought as the traditional counterpart of GB 2312. It is used as an encoding of traditional Chinese characters, although it is not as commonly used as Big5. It has 6,866 characters, and has no relationship nor compatibility with Big5 and CNS 11643
.

Characters

Characters in GB 12345 are arranged in a 94×94 grid (as in ISO/IEC 2022), and the two-byte code point of each character is expressed in the qu-wei form, which specifies a row (qu 区) and the position of the character within the row (cell, wei 位).

The rows (numbered from 1 to 94) contain characters as follows:[2]

  • 01–09: identical to GB 2312, except in row 06 position 57–85, added 29 vertical punctuation forms, and in row 08 position 27–32, added 6 pinyin characters from GB 5007.1–85, the correction of GB 2312.
  • 16–87: arranged the traditional character forms which replaced their simplified forms from GB 2312.
  • 88–89: 103 Chinese characters which is merged due to the simplification of Chinese characters.

The rows 10–15 and 90–94 are unassigned.

Inclusion of non-standard Traditional Chinese characters

GB/T 12345 includes a few traditional characters which is different from the table of correspondences between Simplified Chinese characters and Traditional Chinese characters in the standard Table of General Standard Chinese Characters.

  • 鳧 (57–76): the traditional counterpart of 凫 is 鳬 (2013:3620, page 76), 鳧 is not in the variant form either.
  • 隷 (33–05): the traditional counterpart of 隶 is 隸 (2013:1305, page 60), however 隷 is in the variant form.
  • 𨻶 (47–22): 隙 has no traditional correspondence in the standard.
