Plasma 6.5.4 Wayland: cannot assign ² key as global shortcut for Guake

Hello,

Plasma’s shortcut system does not expose certain non‑alphanumeric keys (like ²) under Wayland.
Would it be possible to support binding ² (and similar layout‑specific keys such as $, ù, etc.) in Plasma’s global shortcut system?

I’ve been using Guake for years with the ² key as my toggle shortcut. On X11 this worked perfectly and became part of my daily workflow.

Since moving to Plasma 6.5.4 (Wayland session), I followed the recommended workaround (System Settings → Keyboard → Shortcuts → add a custom command guake-toggle). This works fine with standard keys, but Plasma does not allow me to assign ² directly. The only way I can trigger Guake now is with Ctrl+², which breaks the muscle memory I’ve built over time.

I’m aware of the Guake issue tracking this limitation on Wayland: Guake GitHub #2127.

Do you know if there is a good reason why most single-key shortcuts like ² cannot be set? If we create a pull request to add this feature, would it be rejected?

Thanks for your help and for all the work on Plasma’s Wayland transition!
