Question

I have a very annoying problem With my Jquery based ajax live search. The search itself is working, but whenever my querystring contains ‘ő’ and ‘ű’ – only these two chars – , the value of the req.getParameter(“sstring”) is null! If the querystring does not have the mentioned chars, it returns the value successfully.
I tried all possible encodings inluding UTF-8 but settled using 8859-2.

    $.ajax({
    type:"GET",
    url: "/myApp/Protected/getStd",
    contentType: "application/x-www-form-urlencoded; charset=iso-8859-2",
    dataType:"application/x-www-form-urlencoded; charset=iso-8859-2",
    data:"sstring="+escape(sstring)+"&options="+id+"&startrow="+startrow+"&valid="+Valid+"&notValid="+notValid+"&searchForm=1",

            async: true,
    success: function(data){
    $("#external").html(data);

    }
 })

I have to highlight that the problem only occures when the querystring is passed by Jquery. If I enter the QueryString to the browser manually the Servlet gets it properly.
Any help is much appreciated.

As per the comments on the question:

INFO: sstring=min%u0151&options=1&startrow=0&valid=true&notValid=true&searchForm=1

The sstring parameter is not properly URL-encoded. You need encodeURIComponent() instead of escape().
