U+8440 "葀" CJK Unified Ideograph-# Unicode Character

U+8440 "葀" CJK Unified Ideograph-# is a rare Chinese character that historically referred to a type of plant, likely a kind of reed or grass used for weaving or medicinal purposes, though its exact botanical identification remains obscure in modern usage. It belongs to the Grass Radical (艹) and carries the phonetic component "舌," but unlike common characters, it is not standard in contemporary Chinese, Japanese, or Korean scripts and appears only in specialized historical or lexicographic contexts. Its meaning and function are thus primarily of interest to scholars of ancient Chinese texts or paleography, as it is seldom encountered in everyday language or computing environments beyond its encoded representation in Unicode.
