The potentially SE-strings only come back when you pass str, and the operating system data isn't properly encoded according to the nominal filesystem encoding. They round trip nicely to other operating system APIs, but can indeed be a problem if they escape to other parts of your program
If the operating system APIs handle SE-strings correctly, is it not acceptable to require the fspath protocol to return strings, and then places like DirEntry or Ethan's module, when they want to return bytes, can just SE-encode the bytes and return those?
Or will the fspath protocol be used at a low enough level that it's below the point where SE-encoded strings are handled properly?
