A few typos in my previous comment, pressed enter too quickly, here's an updated comment: Patch attached with test. In summary: A request to the url b'/\x80' appears to the application as a request to b'/\xc2\x80' -- The issue being the latin1 decoded PATH_INFO is re-encoded as UTF-8 and then decoded as latin1 (on the wire) b'\x80' -(decode latin1)-> u'\x80' -(encode utf-8)-> b'\xc2\x80' -(decode latin1)-> u'\xc2\x80' My patch cuts out the encode(utf-8)->decode(latin1): (on the wire) b'\x80' -(decode latin1) -> u'\x80'
