I don't particularly know, except I think you'd do things like:
environ['PATH_INFO'] = urllib.unquote(http_byte_path).decode('utf8',
Then if the encoding was wrong, you could transcode like:
environ['PATH_INFO'] = environ['PATH_INFO'].encode('utf8',
Note that you need to know the encoding that was used (utf8 in this case)
and that python-escape was used. It has been suggested that the server
should put the encoding it used into the environment. When transcoding this
should also be updated.
It's not clear what python-escape is going to do, I don't think that's been
determined. Probably it'll put \x00 or something in the unicode string to
mark raw bytes.
