Since simplified Chinese conflated many characters into one and since the initial version of the GB encoding scheme, known as GB2312-80, contained only one code point for each character, it is impossible to use GB2312 to map to the bigger set of traditional characters. It is theoretically possible to use Big5 code to map to the smaller set of simplified character glyphs, although there is little market for such a product. Newer and alternative forms of GB have support for traditional characters. In particular, mainland authorities have now established GB 18030 as the official encoding standard for use in all mainland software publications. The encoding contains all East Asian characters included in Unicode 3.0. As such, GB 18030 encoding contains both simplified and traditional characters found in Big-5 and GB, as well as all characters found in Japanese and Korean encodings.
