U+5FDA "忚" CJK Unified Ideograph-# Unicode Character

U+5FDA "忚" CJK Unified Ideograph-# is a rare or obsolete Chinese character that appears in classical texts, though its precise meaning is poorly documented and it is not used in modern standard Mandarin. It is composed of the heart radical (忄) on the left and the phonetic component 也 (ye) on the right, suggesting it may have originally related to a state of mind or emotion, possibly meaning "to become angry" or related to deceit or cunning based on some classical dictionary references, such as the Kangxi Zidian. In modern computing, this character exists primarily for historical and scholarly purposes, enabling the digital representation of ancient or obscure Han characters.
