U+F90E "癩" CJK Compatibility Ideograph-# Unicode Character

U+F90E "癩" CJK Compatibility Ideograph-# is a specialized code point from the Unicode standard's CJK Compatibility Ideographs block, which was designed to preserve the exact character shapes from older East Asian character encoding standards, such as Korean KPS 9566 and other legacy systems, for round-trip compatibility during text conversion. This particular ideograph represents a variant or duplicate of a standard CJK unified ideograph used in the Korean writing system, often corresponding to the character for "ra" or a similar phonetic or semantic element in the Hanja set. Its inclusion in the compatibility block means it is not intended for general new text creation but rather exists to ensure that documents originally encoded in older formats can be accurately displayed and exchanged without losing their original typographic identity.
