I would personally find it useful. I use accented and Chinese
characters, and I've worked in environments where they were common as
well. Having a common name between MUA and FS would certainly be nice.
As for the risks, maybe some Unicode ranges could be restricted to
avoid control characters and such? Or limit the use to given subsets?
It might be useful as well to be able to enable it on a per-user basis.
Would that add too much complexity?
I think of it as a nice feature, but not a critical one.
