The English File's excURL will be correct
The Others Will repeat the path once after returning it
Update: The bug involves parsing the "path" section as both path and host. CreateHostString() returns an empty string for the non-UTF8 path.
The URI construction reaches CreateHostString() with these extra flags on the UTF-8 case: HasUnicode, HostUnicodeNormalized, UseOrigUncdStrOffset, PathIriCanonical. The first one is trivially set by CheckForUnicode(), I am looking into how the process is affected the rest.
This seems to be a regression from: https://github.com/mono/mono/commit/b5dc9a4951bd35b61b29faa4df93bca3c31bfa3e
Commenting out the "newHost = null" fixes the issue. The fix may be to adjust CreateUriInfo instead of removing the host.
Fixed with https://github.com/mono/mono/pull/5778
