忾

U+5FFE "忾" CJK Unified Ideograph-# is a Chinese character (Hanzi) used in both traditional and simplified writing, though it is relatively rare in modern everyday usage.

Structurally, it belongs to the "heart" (忄) radical on the left, indicating its connection to emotions or feelings, combined with a phonetic component.
