How to use ajax with none english letters like (ċ,á,ä,è,ص,ל,מ,ע,...)

I have two pages "test.htm" with the ajax request jscript.
When I write english letters, I got them ok. But when I write none english letters I got ? ?
I modified the line

url=url+"?q="+str

to be

url=url+"?q="+escape(str)

Now I got text like this "c%u010B"

how can i deal with these characters while data stored in none english letters.

Is it clear !!! I tried to use urldecode(); and urlencode() ... is there somthing else

test.htm

<html><head>
<title>ajax test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
var xmlHttp
function showResult(str){
if (str.length==0) { 
 document.getElementById("livesearch").
 innerHTML="";
 document.getElementById("livesearch").
 style.border="0px";
 return
 }
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null){
 alert ("Browser does not support HTTP Request")
 return
 } 

var url="test.php"
url=url+"?q="+escape(str)
url=url+"&sid="+Math.random()
xmlHttp.onreadystatechange=stateChanged 
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
} 

function stateChanged() { 
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete") { 
 document.getElementById("livesearch").innerHTML=xmlHttp.responseText;
 document.getElementById("livesearch").
 style.border="1px solid #A5ACB2";
 } }

function GetXmlHttpObject(){
var xmlHttp=null;
try {
 // Firefox, Opera 8.0+, Safari
 xmlHttp=new XMLHttpRequest(); }
catch (e) {
 // Internet Explorer
 try  {xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");}
 catch (e)  {xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");} }
return xmlHttp;}
</script>
</head>
<body>

<form>
<div class="div1">Live Search</div>
<div class="div2">
<input type="text" id="txt1" size="18" onkeyup="showResult(this.value)">
<div id="livesearch"></div>
</div></form>

</body>
</html>

Thanks for reply.

In javascript there is only thr escape() function I used it in the test.htm

In php urldecode() or rawurldecode() should re generate the text; but where is a problem i don't know where; is it ajax bug?

Please try this:
test.php

<?php 
print $q=$_GET["q"]; 
print "<br />";
print rawurldecode($q);
print "<br />";
print urldecode($q);

//... 
?>

Live Search
Input text: (ċ,á,ä,è,ص,ל,מ,ע,...)

Output:

(%u010B,?,?u0635,%u05DC,%u05DE,%u05E2,...)
(%u010B,?,?u0635,%u05DC,%u05DE,%u05E2,...)
(%u010B,?,?u0635,%u05DC,%u05DE,%u05E2,...)

I found it here:

I had troubles converting Unicode-encoded data in $_GET (like this: %u05D8ב&#1506😉 which is generated by JavaScript's escape() function to UTF8 for server-side processing.

Finally, i've found a simple solution (only 3 lines of code) that does it (at least in my configuration):

<?php
  function utf8_urldecode($str) {
    $str = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($str));
    return html_entity_decode($str,null,'UTF-8');;
  }
?>

note that documentation for html_entity_decode() states that "Support for multi-byte character sets was added at PHP 5.0.0" so this might not work for PHP 4
