U+FA88 "愈" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+FA88 "愈" CJK Compatibility Ideograph-# is a compatibility ideograph included in the Unicode standard specifically to ensure round-trip conversion fidelity with older East Asian character encoding standards, such as certain Japanese industrial standards (JIS) or Chinese GB/T standards, where this specific glyph was a variant or duplicate of a more standard CJK character. It belongs to the CJK Compatibility Ideographs block, which hosts many such forms that were unified with their regular counterparts in later revisions of Unicode but are retained for backward compatibility with legacy text. Despite its appearance, U+FA88 does not represent a distinct new meaning or pronunciation and is generally not used in modern, standardized writing, serving instead as a historical or technical reference for systems that need to map to older encoded character sets.
