Swahili, Hawaiian, Italian, that's just off the top of my head, there are many others.

Hawaiian uses ' as a proper letter, granted.

Doesn't Italian use accented vowels in some cases?

Ah, yes of course it does. Silly me.

None of this detracts from the greater point, being that we need a way for all writing systems to somehow squeeze down into the subset of ASCII supported by legacy protocols.
