Well, that's an implementation detail rather than something the API
guarantees, but OK. It would be nice if the relevant documentation (on
the PC/SC API side as well as the interface for the IFD drivers) would
clearly *mandate* UTF-8 (since your supported chars ⊂ ASCII ⊂ UTF-8).

That way, when a hypothetical generic CCID class driver *does* start to
pull device names out of USB descriptors it can do the right thing.
