The challenge is that string handling in Python 3 is most +conveniently handled with the :class:`str` type eventhough the HTTP protocol +is itself bytes oriented. + +The PEP differentiates so-called *native strings* that are used for +request/response headers and metadata versus *byte strings* which are used for +the bodies of requests and responses. + +The *native strings* are always of type :class:`str` but are restricted to code +points between *u0000* through *u00FF* which are translatable to bytes using +*Latin-1* encoding. These strings are used with :func:`start_response` as +response headers or statuses and must follow :rfc:`2616` with respect to +encoding. That is, they must either be *ISO-8859-1* characters or use +:rfc:`2047` MIME encoding. + +To make the environment accessible using native strings, the :mod:`wsgiref` +module has a new function, :func:`wsgiref.handlers.read_environ` which +transcodes CGI variables from :attr:`os.environ` into native strings and returns +a new dictionary. This function provides a WSGI native string friendly +abstraction which is especially helpful given that the environment variables are +handled differently on various operating systems (native unicode on Windows or +UTF-8 encoded bytes on some Unix installations). + +.. seealso:: + + :pep:`3333` - Python Web Server Gateway Interface v1.0.1 + PEP written by Phillip Eby.
