U+7878 "硸" CJK Unified Ideograph-# Unicode Character

U+7878 "硸" CJK Unified Ideograph-# is a rare and obscure Chinese character, primarily found in historical or specialized contexts rather than modern standard usage. Its composition combines a stone radical with a phonetic component, and it is most commonly associated with the meaning of a millstone or a type of stone used for grinding, though some classical texts suggest it may also refer to a rustic or mountainous region. Because of its rarity, the character is not widely implemented in contemporary fonts or digital input systems, and it typically appears only in ancient literature, dictionaries, or specialized linguistic studies of Chinese characters.
