Package: emacs Version: 1:27.1+1-3.1+deb11u2 1. In gnome, open gnome-characters and emacs. 2. In gnome-characters, find ⋢ (U+22E2) and copy it. 3. Paste it via Ctrl+y to the emacs scratch buffer. 4. Observe that the charater misses a lower bar. In the attached screenshot, on the right you see the correct representation in gnome-characters, and on the left the wrong one in emacs. What you see on the left is the negation of ⊏, whereas you expect the negation of ⊑. In case it's a font issue, please feel free to reassign the bug report appropriately. Gratefully, Alma
