Is there any interest in putting fixup code into wsgiref's CGIHandler? I 
appreciate this is really ugly, but the CGI-to-WSGI gateway is the most 
logical place for this, as otherwise the WSGI environment created by 
CGIHandler often doesn't meet the requirements of the spec.

Trying to fix these problems at an application, framework or middleware 
level is impractical because they don't know that the WSGI environ 
originally came from CGI. (And they can't re-read the environ at that 
point without breaking environ-altering middleware.)

In particular: for Python 2.x running on Win32, read the environment 
using ctypes where available, allowing non-ASCII characters to be read 
directly instead of irretrievably mangled by the ANSI-code-page-encoded 
os.environ interface. Then encode the extracted Unicode environ to byte 
strings using ISO-8859-1, except if the server software is 
Microsoft/IIS, where the encoding will probably be UTF-8.

IIS also needs a fix to remove the duplicated SCRIPT_NAME from the front 
of PATH_INFO. This is a bit more risky as existing apps/libraries may 
already be doing this and might get confused if someone's already done 
the fix. Maybe a subclass like IISCGIHandler?
