+Summary: HttpUtility.UrlDecode from bytes does not work
+
+HttpUtility.UrlDecode(byte[],Encoding) does not properly decode. All
+encoded chars (%xx) are decoded as '\0'. I attach a testcase that works
+under MS.NET and not under mono 1.0. I have look at the implementation, but
+I was unable to figure out quickly what is wrong.
+
+Actual result (Mono):
