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 [1] for usenet posts. [2]: 94 A traditional variant called GB/T 12345 was published in 1990.

'Chinese Characters'), encoding was invented to facilitate the use of Chinese characters through e-mail, which at that time only allowed 7-bit characters. Therefore, in lieu of standard ISO 2022 escape sequences (as in the case of ISO-2022-JP ) or 8-bit characters (as in the case of EUC ), the HZ code uses only printable, 7-bit characters to ...
