U+70B1 "炱" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
炱
U+70B1 "炱" CJK Unified Ideograph-# is a Chinese character that primarily means soot, ashes, or smoke residue, often associated with the black carbonaceous deposits left by burning materials like coal or oil. It is composed of the radical for fire (火) combined with a phonetic component, reflecting its semantic link to fire and combustion byproducts. This character appears in classical and modern Chinese texts, where it can denote physical soot or, by extension, a dark, grimy quality. Its usage is relatively specialized, appearing in contexts related to chemistry, environmental science, or traditional descriptions of smoke damage, and it is not among the most common characters in everyday Chinese writing.
