U+93E5 "鏥" CJK Unified Ideograph-# Unicode Character

U+93E5 "鏥" CJK Unified Ideograph-# is a rare traditional Chinese character used primarily in classical or historical texts, where it denotes the meaning of rust or corrosion, particularly the tarnishing of metal. This character is composed of the metal radical 金 (jīn) on the left and the phonetic component 宿 (sù) on the right, which provides clues to its pronunciation. In modern standard Chinese, this character is largely obsolete, having been replaced by simpler or more common terms such as 锈 (xiù) for rust. Its inclusion in Unicode ensures that scholars and researchers can accurately encode and preserve ancient manuscripts and specialized texts that employ this distinctive glyph.
