I tested it under Windows 11 and, after configuration, it seemed to work. I could not find the Hungarian accents, though, which is one of the things the OP was specifically asking about.
Out of curiosity, if anyone speaks/writes Hungarian ( @pulykamell ?), do the kétpontos (umlaut) and the kettős ékezet (double acute accent) distinguish enough words so that having to employ workarounds can risk getting ones point across in written Hungarian? Or are context clues normally sufficient to handle a strong majority of cases where the proper diacritic can’t be employed?
I’m nowhere near skilled enough in Hungarian to answer definitively, but people would certainly text and email with no diacritics whatsoever, and it would generally be intelligible from context. There is always the potential for confusion, but it can often be managed. I’m sure examples can be drawn up where it’s legitimately ambiguous.
