The keyboard hardware returns raw scancode numbers to my interrupt
handler, so there's no automatic way to support different keyboard
layouts. The conversion into ASCII characters is done with a couple of
lookup tables (found near the start of the file keyboard.c). Change
these tables, and all will be well...

As a more elegant solution, if you can send me suitable tables for a
Swedish keyboard and tell me how to detect when they should be used
(some DOS call, I suspect), I'll include them in the next release of
Allegro. Or even better, if anyone knows how to access the scancode-
>ascii mapping being used by DOS itself, I'd really like to know about
it! I suspect the gory details will differ between different OS
versions, but it would be nice if it could be done...
