(Spring + JSP + jQuery-AJAX + JSON) configurando el entorno para el problema de UTF-8?

Estoy haciendo unchat project enjava conSpring 3.x que necesitaMulti-language support.

Esto es lo que he hecho.

Mi JSP tiene:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%request.setCharacterEncoding("UTF-8"); %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

Miweb.xml tiene:

<filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

En miTomcat server.xml tiene:

  <Connector (...) URIEncoding="UTF-8" />

Mi miJava environment tiene:

  JAVA_TOOL_OPTIONS     -Dfile.encoding=UTF8

En miSpring-controller tiene:

@RequestMapping(value="sendMessage.html",method=RequestMethod.POST)
public  @ResponseBody String sendMessage(HttpSession session,@RequestParam String intxnId,@RequestParam String message, HttpServletRequest request,HttpServletResponse response){

        String contentType= "text/html;charset=UTF-8";
        response.setContentType(contentType);
        //response.setCharacterEncoding("UTF-8");
        response.setHeader("Content-Type", "application/json; charset=UTF-8");
        try {
            request.setCharacterEncoding("utf-8");

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        response.setContentType("text/plain;charset=UTF-8"); 

        System.out.println("Send Message UTF-8 ----------------- "+ message);

    String json = null;
    BasicChatProtocol protocol = CustomerManagement.protocol.put(intxnId, chatProtocol.getProtocol());
    HashMap<String,String> result = send.send(message, intxnId, protocol);
    result.put("name",(String) session.getAttribute("nickName"));
    ObjectMapper map = new ObjectMapper();
    if(result.size()!= 0){
        try {
            json = map.writeValueAsString(result);
            result.clear();
            result = null;
            System.out.println("Send Message  :::::::: : "+json);
        } catch (Exception e) {
            e.printStackTrace();
        } 
    }
return json;

}

MijQuery-AJAX estarán:

function sendMessage(){
    var intxnId = $("#hide").val();
    var message = $("#message").val();
    alert("send  : \n intxnId : "+intxnId+"\nmessage : "+message);
    $.ajax({  
        type: "POST", 
        cache: false,
        url: contexPath + "/sendMessage.html",
        async:     true,
        contentType: "application/x-www-form-urlencoded; charset=utf-8",
        scriptCharset: "utf-8",
        dataType: 'html',
        data: "intxnId=" + intxnId +"&message="+ encodeURIComponent(message),

        success: function(response){

            if(response != null && response !="" && response !="null"){

                var txt = '{"data":['+response+']}';
                var json = eval ("(" + txt + ")");
                for(i =0;i<json.data.length;i++){
                    var data = json.data[i];

                    var name = data.name;
                    var message = data.message;
                    var time = data.time;

                    alert("Name : "+name+"\nMessage : "+message+"\ntime : "+time);
                    var createHTML  = send(name,message,time);
                    $("#messageDisplayArea").append(createcreateHTML);
                };
            }

        },  
        error: function(e){  
            alert('Error: ' + e);  
        }, 

    }); 
}

Pero cuando envío el mensaje en idioma localஅவர்களுக்கு(Idioma tamil), solo tengo??????? en elalert box y elview page.

Pero tengo ellocal language en la consola (SysOut in controller) y todoSpecial Characters trabajos.

Nota : Creo que estoy teniendo el problema conresponse from the controller.Porque cuando envío elmessage alcontroller tengo elmessage as small boxes enjavascript alert. Pero cuando elresponse vino estoy recibiendo el????? en elalert box.

Mi consola imprime,

Send Message UTF-8 ----------------- அவர்களுக்கு
Mesge what I send :::: அவர்களுக்கு
Send Message :::::::: : {"message":"அவர்களுக்கு","time":"time","name":"Human"}

No sé lo que me estoy perdiendo.

Nota : No estoy usando ningunadata base.
