The Guobiao (GB) line of character encodings start with the [[Simplified Chinese]] charset [[GB 2312]] published in 1980. Two encoding schemes existed for GB 2312: a one-or-two byte 8-bit [[EUC-CN]] encoding commonly used, and a 7-bit encoding called [[HZ (character encoding)|HZ]]<ref>{{IETF RFC|1843}}</ref> for usenet posts.<ref name="cjkv-info-proc">{{cite book|last1=Lunde|first1=Ken|title=CJKV Information Processing|date=December 2008|publisher=O'Reilly Media, Inc|isbn=978-0-596-51447-1|url=https://books.google.com/books?id=SA92uQqTB-AC|accessdate=11 September 2016}}</ref>{{rp|94}} A traditional variant called [[GB/T 12345]] was published in 1990.

The EUC-CN form was later extended into [[GBK (character encoding)|GBK]] to include ''all'' Unicode 1.1 CJK Ideographs in 1993, abandoning the ISO-2022 model. By doing so, GBK includes [[traditional Chinese characters]] in addition to simplified ones in GB2312.<ref>{{Cite web|url=http://developers.sun.com/dev/gadc/technicalpublications/articles/gb18030.html |title=GB18030-2000 – The New Chinese National Standard – GB 18030 |date=2012-08-25 |access-date=2016-10-13 |url-status=bot: unknown |archiveurl=https://web.archive.org/web/20120825155118/http://developers.sun.com/dev/gadc/technicalpublications/articles/gb18030.html |archivedate=2012-08-25 }}</ref> GBK gained popularity through the widespread [[Code page 1386|Code page 936]] implementation found in Microsoft Windows 95.

In 2000, [[GB 18030]] was published as GBK's successor. This new encoding includes a four-byte UTF which encodes all Unicode codepoints not previously encoded.<ref>[http://source.icu-project.org/repos/icu/data/trunk/charset/data/xml/gb-18030-2000.xml Authoritative mapping table between GB18030-2000 and Unicode].

[[PostScript fonts#Adobe-GB1|Adobe-GB1]] is the corresponding PostScript charset for GB encodings.
