The CNS 11643 character set (Chinese National Standard 11643), also officially known as the Chinese Standard Interchange Code or CSIC (Chinese: 中文標準交換碼), is officially the standard character set of Taiwan (Republic of China). Published and draft editions of CNS 11643 remain the source standards for Unicode reference glyphs for CJK Unified Ideographs submitted for use in Taiwan, and the character repertoire of CNS 11643 continues to be updated and used for administrative purposes in Taiwan.
EUC-TW is an encoded representation of CNS 11643 and ASCII in Extended Unix Code (EUC) form. In practice, variants of the Big5 character set, which is closely related to the first two planes of CNS 11643, served as the de facto standard encoding for Traditional Chinese before the introduction of Unicode. 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).
