U+51FE "凾" CJK Unified Ideograph-# Unicode Character

U+51FE "凾" CJK Unified Ideograph-# is a rare and complex Chinese character traditionally used as a variant of the more common character "函" (hán), which signifies a case, box, envelope, or letter. It is composed of the enclosure radical (凵) combined with internal strokes, and while its usage in modern standard Chinese is extremely limited, it occasionally appears in historical texts, calligraphy, or proper names where traditional or ornate forms are preferred. This character belongs to the CJK Unified Ideographs block and is encoded for compatibility with older character sets, reflecting the breadth of the East Asian script repertoire.
