U+864B "虋" CJK Unified Ideograph-# Unicode Character

U+864B "虋" CJK Unified Ideograph-# is an exceptionally rare and obscure Chinese character that represents a type of bean plant, specifically referring to the "red bean" or "azuki bean" in classical texts, though it is often associated with a more general meaning of a kind of grain or herb in ancient dictionaries. This character is composed of the radical for "grass" or "plant" (艹) over a complex phonetic component, and it appears primarily in historical or literary contexts, such as in the Erya, an early Chinese dictionary, where it is defined as a type of legume. Due to its extreme rarity and lack of modern usage, "虋" is sometimes noted as one of the most complex and rarely used characters in the CJK Unihan repertoire, with very few digital fonts including it and virtually no contemporary application outside of specialized calligraphy or paleographic study.
