A long thread of discussion covering the PEP 333 and the decoding of the PATH_INFO attribute in the environ dict. Final verdict – its sucks, but it should be decoded. Reason being the CGI spec, which the PEP 333 refers to says so. I encountered this issue when I noticed that wsgi-inspect does not actually decode the PATH_INFO attribute.

A useful tool when you need a simple tool to code and decode strings quickly.
