U+9F21 "鼡" CJK Unified Ideograph-# Unicode Character

U+9F21 "鼡" CJK Unified Ideograph-# is a rare or obsolete Chinese character that functions as a variant form of the more common character 鼠 (shǔ), meaning "rat" or "mouse." It appears in certain classical texts and historical contexts, where it was used to represent the rodent or the first earthly branch in the Chinese zodiac, though it is seldom employed in modern writing. Its structure combines the radical 鼠 (rat) with a phonetic or semantic component, reflecting the complexity of traditional character variants in the CJK (Chinese, Japanese, Korean) unified ideograph system.
