[Web-SIG] PEP3333 and PATH_INFO

[Chris McDonough]

Perrenial topic, it seems, from the archives.

As far as I can tell from PEP 3333, every WSGI application that wants to
run on both Python 2 and Python 3 and which uses PATH_INFO will need to
define a helper function something like this:

"""
import sys

def decode_path_info(environ, encoding='utf-8'):
    PY3 = sys.version_info[0] == 3
    path_info = environ['PATH_INFO']
    if PY3:
        return path_info.encode('latin-1').decode(encoding)
    else:
        return path_info.decode(encoding)
"""

Is there a more elegant way to handle this?
