U+FAC8 "靖" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+FAC8 "靖" CJK Compatibility Ideograph-# is a specialized character within the CJK Compatibility Ideographs block, a collection of characters primarily intended to represent forms used in legacy East Asian character sets for roundtrip compatibility with older encoding standards. This particular ideograph, while visually similar to a standard Chinese, Japanese, or Korean character, is defined not for modern writing but for preserving the exact glyph shape and mapping from a pre-Unicode source, such as a vendor specific or national standard code page. Its inclusion in Unicode helps ensure that text originally encoded in systems like the Apple, IBM, or Japanese JIS X 0213 standards can be converted without information loss, though it is generally recommended to use the corresponding unified CJK Unified Ideograph for new text. As a compatibility character, U+FAC8 is rarely used in contemporary documents and serves more as a technical bridge between older and newer encoding systems.
