U+78B5 "碵" CJK Unified Ideograph-# Unicode Character

U+78B5 "碵" CJK Unified Ideograph-# is a rare or obsolete Chinese character that primarily appears in historical or classical texts, often associated with meanings related to stone, firmness, or a specific type of mineral substance, though its exact usage and definition can vary across different sources. It is composed of the radical for stone (石) and a phonetic component, which suggests it may have been used to denote a kind of hard stone or a metaphorical sense of sturdiness. Due to its infrequent occurrence in modern Chinese, Japanese, or Korean, it is not commonly found in everyday language but may be encountered in specialized contexts such as historical linguistics, calligraphy, or the study of ancient inscriptions.
