I don't know how that related to WSGI but it should be noted that Python 3.2
comes with two synchronized views of the environment: os.environ (str -> str
mapping) and os.environb (bytes -> bytes mapping).
Also, the way os.environ is decoded from bytes values involves the
"surrogateescape" error handler, which ensures that non-decodeable bytes get
their own unicode escape sequences, and can get re-encoded losslessly:
