U+78AF "碯" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
碯
U+78AF "碯" CJK Unified Ideograph-# is a rare and archaic Chinese character composed of the radical for "stone" (石) on the left and the phonetic component "脑" (nǎo) on the right. It traditionally refers to a type of gemstone or precious stone, often specifically identified as a kind of agate or carnelian, and appears in classical Chinese texts such as ancient dictionaries and poetry with connotations of hard, ornamental mineral objects. In modern usage, the character is largely obsolete, having been supplanted by more common characters for similar meanings, and it is primarily of interest to scholars of historical Chinese calligraphy, lexicography, and paleography.
