What use case are we discussing here?

Is it the one where the user gets a path from an external source and passes
it to Nowide? In which case Nowide does no validation on POSIX and strict
UTF-8 validation on Windows? Giving the Windows user the false assumption
that Nowide validates, which turns out to not happen in a later POSIX port.

Or is it the one where the user receives a path from Nowide? Which currently
doesn't occur anywhere, because the library does not return paths, it only
takes them as arguments. (It would occur if you add `readdir`.)

How would portable user code look like in this scenario?
