U+78A1 "碡" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

碡

U+78A1 "碡" CJK Unified Ideograph-# is a rare Chinese character composed of the stone radical on the left and a phonetic component related to "pronunciation" or "reading" on the right, though its exact meaning varies across historical and regional contexts. In classical Chinese, it sometimes refers to a type of stone implement or a grinding tool, often associated with agricultural or industrial processes in ancient texts, but it is not commonly used in modern standard Mandarin. The character appears in specialized literary or historical works, such as in descriptions of millstones or stone rollers, and may also function as a component in personal names or obscure place names. Its encoding in Unicode ensures that this obscure but culturally relevant glyph remains accessible for digital preservation and scholarly research.
