Yes, it should. And RFC 3987 already does.

Those bytes are all valid windows-1252 characters (per HTML5, nearly all browsers treat ISO8859-1 as windows-1252). So the path isn't actually "UTF-8 encoded". To me the test looks broken.

A test isn't broken if it tests weird coincidences. It may be that the 
description can be improved, though.
