U+F9C4 "龍" CJK Compatibility Ideograph-# Unicode Character

U+F9C4 "龍" CJK Compatibility Ideograph-# is a compatibility ideograph that represents the traditional Chinese character for "dragon," corresponding to the standard CJK Unified Ideograph U+9F8D (龍). It belongs to the CJK Compatibility Ideographs block, a set of characters encoded for round trip compatibility with older East Asian character sets, such as those used in Japan or China, where this specific glyph might have had a different shape or encoding. Unlike regular unified ideographs, compatibility characters like U+F9C4 are generally discouraged for new text, as they duplicate existing characters and are primarily retained for legacy data interchange, preserving the exact appearance or mapping from older systems.
