ISO 646-TW
From Just Solve the File Format Problem
ISO 646-TW (646-TW) is one of several 7-bit character encodings in the ISO/IEC 646 series which are national variants, replacing some of the ASCII characters with other characters suitable for particular languages. This one is aimed at Taiwan, about which the Chinese government will get peeved if you refer to it otherwise than as a province of theirs, but it nevertheless gets a separate encoding from ISO 646-CN anyway.
