//Characters in GB2312 are divided into codepoints, with each codepoint comprising 94 glyphs/characters.

//

//The codepoints can be divided and categorised as:

//    * 01-09, comprising punctuation and other special characters.

//    * 16-55, the first plane for chinese characters, arranged according to Pinyin.

//    * 56-87, the second plane for chinese characters, arranged according to radical and strokes.

//

//The codepoints 10-15 and 88-94 are unassigned.
