U+787F "硿" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

硿

U+787F "硿" CJK Unified Ideograph-# is a Chinese character (hanzi) that belongs to the "CJK Unified Ideographs" block, representing a specific logographic glyph used in historical and modern Chinese writing. Its primary meaning relates to a type of stone or rocky substance, often found in classical texts or compound words describing mineral or geological features, though it is considered a rare or obscure character in contemporary usage. The character is composed of the radical "石" (stone) on the left, indicating its semantic association with rock or stone, and the phonetic component "空" (kōng, meaning empty or hollow) on the right, which suggests its pronunciation. As a unified ideograph, it is recognized across multiple East Asian writing systems, including Chinese, Japanese, and Korean, though its frequency and practical application vary by region and historical context.
