This task   (the reverse of   URL encoding   and distinct from   URL parser)   is to provide a function
or mechanism to convert an URL-encoded string into its original unencoded form.



Test cases

   The encoded string   "http%3A%2F%2Ffoo%20bar%2F"   should be reverted to the unencoded form   "http://foo bar/".
   The encoded string   "google.com/search?q=%60Abdu%27l-Bah%C3%A1"   should revert to the unencoded form   "google.com/search?q=`Abdu'l-Bahá".


 
void main()
{
    array encoded_urls = ({
        "http%3A%2F%2Ffoo%20bar%2F",
        "google.com/search?q=%60Abdu%27l-Bah%C3%A1"
    });
 
 
    foreach(encoded_urls, string url) {
        string decoded = Protocols.HTTP.uri_decode( url );
        write( string_to_utf8(decoded) +"\n" ); // Assume sink does UTF8
    }
}
