U+FA1E "羽" CJK Compatibility Ideograph-# Unicode Character

Unicode Version 17.0

U+FA1E "羽" CJK Compatibility Ideograph-# is a compatibility ideograph that represents an alternate or historical glyph variant of the standard CJK unified character for "feather" or "wing," which is normally encoded as U+7FBD "羽." Originally sourced from the Japanese industrial standard JIS X 0208 for compatibility with older text encoding systems, this character is considered a duplicate of the unified ideograph and is generally not recommended for use in new documents, as its primary purpose is to preserve the exact roundtrip conversion of legacy data. Its inclusion in Unicode highlights the effort to maintain textual fidelity when migrating from earlier character sets, even though the same meaning can be expressed by the common "羽" character.
