U+FA04 "宅" CJK Compatibility Ideograph-# Unicode Character

U+FA04 "宅" CJK Compatibility Ideograph-# is a compatibility ideograph from the CJK (Chinese, Japanese, and Korean) block, specifically encoded for roundtrip compatibility with older character set standards, where it represents a variant form of the East Asian character for "dwelling" or "house," corresponding to the standard CJK Unified Ideograph U+5B85 (宅). It was included in Unicode to preserve the precise mapping of characters from legacy encoding systems, such as those used in Japan, though it is generally considered a duplicate of the unified character and is not recommended for use in modern text, as it exists primarily for historical data interchange and documentation.
