[issue16679] Wrong URL path decoding

[Claude Paroz]

Claude Paroz added the comment:

I may understand your reasoning when you cannot make any assumptions about the encoding of a series of bytes.

I think that the case of PATH_INFO is different, because it should comply with standards, and then you *can* make the assumption that the original path is 'utf-8'-encoded. So either leave the string undecoded, or decode it to what the standards say. It would put un unneccessary burden on WSGI apps to always require to encode-redecode this string.
Wouldn't it be possible to amend PEP 3333?

Hopefully we can get some other opinions about this issue.
