I am maintaining a code in which users response is encoded in JavaScript using escape and then decoded in Java Code using URLDecoder.decode.
It works perfectly but recently it starts breaking for Smart Quotes like “, ”.

I see that escape converts smart quote like “test” in %u201Ctest%u201D.
However, when I try decoding it as


it throws the exception
%u201C exception java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern

I did some google and advise was to use encodeURI or encodeURIComponent.

If I use these, “test” gets converted to %E2%80%9Ctest%E2%80%9D but now when I use UrlDecoder it gives me

Please advise what is the best way to do encode-decode when you do encoding in Java Script and decoding in Java.
