KVP 8 bits support

A KVP query with 8 bits char (ä for example) is not rightly handled (url_decode only handle 7 bits)

From RFC1738:

Octets must be encoded if they have no corresponding graphic
character within the US-ASCII coded character set, if the use of the
corresponding character is unsafe, or if the corresponding character
is reserved for some other interpretation within the particular URL
scheme.

so, passing ä in a url in invalid.

Thanks Thomas for this input, i close this ticket accordingly

Not sure this should be closed yet. ä is properly encoded to %E4 in the provided url.
