decode_URI: simplify/relax non-encoded characters handling

Browse Source 
Since non-ASCII or non-printable characters are not supposed to occur
in URL, it does not matter much how they are dealt with.

The caller of decode_URI() can anyway not assume anything about the
decoded string. In particular, decode_URI() does not validate UTF-8
sequences in any case.
