I'm not really thrilled with the idea of encoding different values
differently, because it means that many more things for an
implementer to remember to do correctly, but for which they receive
no guidance or error messages if they get it wrong at first.
One big benefit of surrogateescape is that it maintains a certain
symmetry between Python 2 and 3 wrt os.environ and CGI. That is, you
can in principle just throw a few extra keys into a copy of
os.environ and have a valid wsgi environment. (At least, in places
where the system encoding is utf8, anyway.) If you don't make it
uniform across all CGI keys, then you have to write more a complex
adapter, and at every level you need to remember what sort of key
