Stephen J. Turnbull a écrit :
What really saves the day here is not that "common encodings just
don't do that". It's that even in the case where only syntactically
significant bytes in the representation are URL-encoded, they *are*
URL-encoded. As long as the parsing library restricts itself to
treating only wire-format input, you're OK.[1] But once you start
doing things that involve decoding URL-encoding, you can run into
trouble.
If I understand you well, any processing of unquoted bytes is dangerous per se.
If this is true, then perhaps 'unquote' doesn't disserve the criticism it
received in this thread for always returning str. This would be in fact quite
fortunate, as it forces url processing to either happen on quoted bytes (before
calling 'unqote'), or on unquoted str (on the result of 'unquote'), both of
which are safe.
