Foreword
In this Standard, the part of single-byte code, the part of double-byte code, and
the part of CJK unified Chinese character extension A (i.e., 0x8139EE39-
0x82358738) of the part of four-byte code are mandatory.
This Standard replaces GB 18030-2000 "Information technology - Chinese ideograms
coded character set for information interchange - Extension for the basic set".
Compared with GB 18030-2000, it adds the number of coded Chinese characters and
supplementally stipulates the code position of some minority languages of China in this
Standard. This Standard redefines the coding position of the character " ". The coding
architecture of this Standard remains unchanged.
Annex A, Annex B, Annex C, Annex D and Annex E of this Standard are normative.
This Standard was proposed by Ministry of Information Industry of the People's
Republic of China.
This Standard shall be under the jurisdiction of China Institute of Electronic Technology
Standardization.
