U+F977 "亮" CJK Compatibility Ideograph-# Unicode Character

U+F977 "亮" CJK Compatibility Ideograph-# is a compatibility ideograph from the CJK Compatibility Ideographs block, which was encoded primarily to maintain round-trip compatibility with older East Asian character set standards like CNS 11643 or certain vendor-specific encodings. This particular character represents a variant form of the standard CJK Unified Ideograph "亮" (meaning bright or light), but it is visually distinct in some legacy representations and serves as a mapping point for systems that historically used a slightly different glyph shape. Unlike typical unified ideographs, U+F977 is not intended for general modern text and is often treated as a duplicate or alternate form, with its use discouraged in favor of the unified version in the main CJK block.
