Is this fixing an actual bug that you have encountered? I'm mostly
asking because I think this actually works as inteded: we only try to
decode the path using the specified encoding in case where it is not
representable as ASCII. If it contained e.g. Unicode characters, then
this statement here would throw and we end up decoding in the `except`
branch. Otherwise, we know that the path only contains ASCII characters
and thus we don't have to change it in the first place.

Whether that complexity is sensible might be a different question. But
it at least shouldn't result in any user visible bug, no?
