One way to decode using plain sh scripts is to substitute each % with \x
and pass the string to printf, but I don't know how solid it can be in
the real world

	$ QUERY_STRING='caf%C3%A8'
	$ printf '%b\n' $(printf "%s\n" "$QUERY_STRING" | sed 's/%/\\x/g')
	caf?

Or you can shell out to python, ruby, perl, etc... that have libraries
to do the decoding.
