U+FA63 "謹" CJK Compatibility Ideograph-# Unicode Character

U+FA63 "謹" CJK Compatibility Ideograph-# is a compatibility ideograph that represents the Chinese character "謹" (jǐn), meaning "cautious" or "respectful," but encoded in a specialized block designed for roundtrip compatibility with older character encoding standards like CNS 11643 and Shift JIS. It belongs to the CJK Compatibility Ideographs block, which contains characters that were unified with other CJK characters in the main Unicode CJK Unified Ideographs block, but are preserved here to maintain compatibility with legacy systems. This character is generally not recommended for modern text because the unified version (U+8B39) should be used instead, and its presence in the compatibility block ensures that documents encoded in older standards can be converted without loss of data.
