U+5FDF "忟" CJK Unified Ideograph-# Unicode Character

U+5FDF "忟" CJK Unified Ideograph-# is a rare and obscure Chinese character that traditionally means "brave" or "fierce," often associated with a state of agitation or irascibility, though its usage is extremely limited in modern standard Chinese, surviving primarily in historical or classical texts. Composed of the heart radical (忄) on the left and the phonetic component "文" (wén) on the right, it is sometimes considered a variant or archaic form of more common characters like "忞" (mín) or "愍" (mǐn), which connote effort, strength, or pity. In the Unicode standard, it belongs to the CJK Unified Ideographs block, coded for compatibility with East Asian text encoding systems.
