U+78BF "碿" CJK Unified Ideograph-# Unicode Character

U+78BF "碿" CJK Unified Ideograph-# is a rare Chinese character (hanzi) classified as part of the Kangxi radical 112 (石, meaning "stone"). Its exact meaning is obscure, appearing in ancient or historical texts with possible references to a type of stone or mineral substance, though it is not commonly used in modern Chinese or Japanese. The character is composed of the stone radical on the left and a phonetic component on the right, reflecting its formation as a phono-semantic compound. In contemporary contexts, it may appear in specialized dictionaries, historical inscriptions, or as part of the Unicode standard for encoding rare or complex CJK characters.
