Support non-English keyboards

[amab8901]

My keyboard is Swedish rather than English. I think Theseus should add support for that. Doing so will make it easier for me (and other international contributors) to work with Theseus because the character written on the keyboard buttons will then correspond to what's produced on the screen and the user/contributor won't have to rely on trial-and-error to write a given character

Sure, feel free to open a PR; I'd be happy to help guide it. It'd certainly be nice to have, as would support for unicode, which I assume would also be required in order to print said international characters.

Unfortunately, no one on the core Theseus team has hardware to test that nor the bandwidth to devote to it currently.
