jquery url에 중국어 왜곡 문자가 전달되면 어떻게 해야 할까요?

ajaxSettings:{url:location.href,global:true,type:"GET",contentType:"application/x-www-form-urlencoded;charset=UTF-8",processData:true,async:true,xhr:function(){return new E.XMLHttpRequest}

function confirmcommit(){
 
    var wlCompany = $("#wlCompany").val();//这里含有中文
    var wlId = $("#wlId").val();
    var proposer = $("#proposer").val();
    if(confirm("确认要换货吗")){
$.ajax({
type:'POST',
url:'${pageContext.request.contextPath}/returnGoods/confrimExchangeGoods.do',
data:'wlCompany='+wlCompany+'&wlId='+wlId+'&proposer='+proposer, //直接传值
dataType:'text',
error:function(){
    alert("JQuery AJAX Error!");     
},
success:function(msg){
    alert(msg);
    return;
    if(msg=='换货成功'){
 document.location="${pageContext.request.contextPath}/orderItem/queryProduceItem.do?orderBusType="+${orderBusType};
    }
}
});
     }
 }

public ActionForward confrimExchangeGoods(ActionMapping mapping,
 
ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
log.info("确认换货 confrimExchangeGoods start...............");
response.setCharacterEncoding("UTF-8"); //这里要设置一下
String wlCompany = request.getParameter("wlCompany");
String wlId = request.getParameter("wlId");
String proposer = request.getParameter("proposer");
     .....
}
