U+6639 "昹" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
昹
U+6639 "昹" CJK Unified Ideograph-# is a rarely used Chinese character composed of the sun radical (日) on top and the phonetic component "衣" or a related variant below, though its precise meaning is obscure and it does not appear in modern standard Mandarin dictionaries. It is classified as a CJK (Chinese, Japanese, Korean) ideograph within Unicode's unified character set, intended to encode historical or uncommon logographs from classical texts. In practice, "昹" is seldom encountered in contemporary digital communication, and its usage is largely limited to specialized contexts such as ancient literature or genealogical records where it may function as a personal name or a transcription of an old term.
