U+55D8 "嗘" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

U+55D8 "嗘" CJK Unified Ideograph-# is a rare and archaic Chinese character that belongs to the CJK (Chinese, Japanese, and Korean) Unified Ideographs block. Its meaning is obscure and not commonly used in modern Chinese, Japanese, or Korean texts, with historical records suggesting it may have represented a sound or onomatopoeic expression, possibly related to laughter or a sharp noise. The character is composed of the mouth radical (口) on the left, indicating its association with vocal sounds, and the phonetic component on the right, though its exact etymology and usage remain largely undocumented in standard dictionaries. As a result, it is primarily encountered in specialized contexts such as historical character encodings or rare script collections.
