U+F922 "濫" CJK Compatibility Ideograph-# Unicode Character

U+F922 "濫" CJK Compatibility Ideograph-# is a specialized glyph found in the CJK Compatibility Ideographs block, a collection of characters originally encoded to maintain roundtrip compatibility with older East Asian character set standards like CNS 11643 and JIS X 0213. This particular ideograph represents a variant or duplicate form of the standard CJK Unified Ideograph U+6FDB "濫", which means "overflow", "excess", or "abuse" in Chinese and Japanese. It was included in the Unicode standard to preserve the exact duplicate code points present in those legacy encoding systems, ensuring that text converted from those older formats would retain its original appearance. In modern usage, U+F922 is generally considered a compatibility character and is not recommended for new text, as the unified version U+6FDB is preferred for representing the same character.
