My Danish street address includes non-ASCII letters.

There are easy transliterations, but I input them on my British accounts to make a point. About half work correctly.

Avoding any international characters, both when registering addresses and when inputting them in forms ends up being the path towards hopefully being able to spend money with credit/debit cards though. For various other non financial forms fuzzing the systems with what should be common enough european text and laughing as it fails is safer fun though.
