Apple also uses certain single-byte codes outside of the EUC-KR plane for additional characters: 0x80 for a required space, 0x81 for a won sign (₩), 0x82 for an en dash (–), 0x83 for a copyright sign (©), 0x84 for a wide underscore (＿) and 0xFF for an ellipsis (…). Although none of these additional single-byte codes are within the lead byte range of plain EUC-KR (unlike Apple's extensions to EUC-CN, see above), some are within the lead byte range of Unified Hangul Code (specifically, 0x81, 0x82, 0x83 and 0x84).
