In general, I think it would help the UX to have a switch labeled "Old-school / Windows" which would help taking two different paths:
- the Old-school for generating the classic key sequence.
- the Windows for using Alt-key escapes.
Exotic systems probably won't support for Alt-Keys (it's a Windows thing, right?) or tend to use non-English keyboard layouts less frequently.
So users of both typical and exotic systems might benefit from it.
Then the Mac+Linux desktops having non-English layouts activated would probably be hardest to work around.
