U+FA5C "臭" CJK Compatibility Ideograph-# Unicode Character

U+FA5C "臭" CJK Compatibility Ideograph-# is a compatibility ideograph from the CJK Compatibility block, specifically representing a variant or duplicate form of the standard Chinese character "臭" (chòu), which means "stinky" or "foul smelling." This character was included in Unicode to maintain roundtrip compatibility with older East Asian encoding standards such as JIS X 0213, where it appears as a distinct coded character despite having an identical semantic and orthographic counterpart in the unified CJK Unified Ideographs block. As a result, it is considered a duplicate character for modern use, and its primary purpose is to preserve historical text data rather than to be used in new writing, with a recommendation to employ the unified version U+81ED "臭" instead.
