U+FA80 "婢" CJK Compatibility Ideograph-# Unicode Character

U+FA80 "婢" CJK Compatibility Ideograph-# is a specialized glyph found within the CJK Compatibility Ideographs block, a section of Unicode designed to preserve the exact shapes of characters used in older, pre-standardized East Asian character sets such as those from Japan's Shift JIS encoding. This particular character is mapped to a specific ideograph that represents the hanzi or kanji for a word meaning "a legendary wild beast," specifically the mythical creature known as the "kui" or "one-legged dragon" in Chinese mythology. It exists primarily for round-trip compatibility with legacy systems, ensuring that documents and data converted from older encodings retain their original visual form, though modern Unicode practice encourages users to employ the standard unified CJK character U+591A for general text instead.
