The CNS 11643 character set (Chinese National Standard 11643), also officially known as the Chinese Standard Interchange Code or CSIC[1] (Chinese: 中文標準交換碼), is officially the standard character set of Taiwan (Republic of China). In practice, variants of the related Big5 character set are de facto standard.
CNS 11643 is designed to conform to ISO 2022. It contains 16 planes, so the maximum possible number of encodable characters is 16×94×94 = 141376. Planes 1 through 7 are defined by the standard; since 2007, planes 10 through 15 have also been defined by the standard.[2]: 115–122 Prior to this, planes 12 to 15 (35344 code points) were specifically designated for user-defined characters.[citation needed] Unlike CCCII, the encoding of variant characters in CNS 11643 is not related.
EUC-TW is an encoded representation of CNS 11643 and ASCII in Extended Unix Code (EUC) form. Other encodings capable of representing certain CSIC planes include ISO-2022-CN (planes 1 and 2) and ISO-2022-CN-EXT (planes 1 through 7).
