Other EUC-CN variants deviating from the EUC mechanism include the Mac OS Chinese Simplified script (known as Code page 10008 or codice_1). It uses the bytes 0x80, 0x81, 0x82, 0xA0, 0xFD, 0xFE and 0xFF for the U with umlaut (ü), two special font metric characters, the non-breaking space, the copyright sign (©), the trademark sign (™) and the ellipsis (…) respectively. This differs in what is regarded as a single-byte character versus the first byte of a two-byte character from both EUC (where, of those, 0xFD and 0xFE are defined as lead bytes) and GBK (where, of those, 0x81, 0x82, 0xFD and 0xFE are defined as lead bytes).
