U+5518 "唘" CJK Unified Ideograph-# Unicode Character

U+5518 "唘" CJK Unified Ideograph-# is a Chinese character that is a less common variant of the more standard "啟" or "启", both meaning "to open", "to begin", "to start", or "to enlighten". It is composed of the radical "口" (mouth) and "攵" (a variant of "攴", indicating action), with "户" or "戶" (door) implicitly structuring its form. This character appears in classical or historical texts as part of the CJK (Chinese, Japanese, Korean) unified ideograph set, primarily in traditional Chinese usage, and is encoded for digital representation to preserve historical and regional written variants of the Chinese script.
