[🐞 BUG] keyboard shortcut UI doesn't render `§`/`±` key

[shhac]

Describe the bug
If you assign a hotkey to use the section sign/plus-minus key, then the UI will show the selected hotkey as an empty box, or a modifier plus end of input.

On an Apple UK keyboard layout, this key is located On the left edge of the keyboard between the esc and tab keys, to the left of key 1.

To Reproduce
Steps to reproduce the behavior:

1. Go to: Preferences > Global Hotkey.
2. Click on Change for any of the hotkeys.
3. Press the section sign key, with or without any modifier keys.
4. Witness the UI showing currently selected hotkey become a blank box or the modifier key without the section sign key.

Expected behavior
The currently selected hotkey UI should show the section sign symbol along with any modifier.
