Describe the bug

at least on Windows 10 (and I think it happens on MacOS as well) these shortcuts only work in layouts with Latin characters, such as English (United States). this is because the code checking for special shortcuts operates on logical, not physical keys:

• 2024-02-21 00:54:51.1492981 [TRACE] (1) egui_winit: logical Character("с") -> None,  physical Code(KeyC) -> Some(C)
  

(this is present in at least egui v0.25.0, and it doesn't look like it's fixed in the current master branch, b804857)

To Reproduce

try copying any text from a text field while having a keyboard layout without a Latin character on the C hardware key
