my ajax project

[harmor19]

Well the ajax is going well but it doesn't return special characters
Here's what the username is supposed to look like G?? Th? ?m??r??L?
But on the ajax form it returns it as G�� Th� �m��r��L�

Here's the site http://www.rapinfluence.com/board/testing/test.html
Just put a random userid in and click out of the box.

Edit:
If I go thrugh the address bar it shows up fine http://www.rapinfluence.com/board/te...me.php?param=1
so it has to be on the js side.

<script language="javascript"  type="text/javascript">
var url = "getusername.php?param="; // The server-side script
function handleHttpResponse() {
  if (http.readyState == 4) {
    // Split the comma delimited response into an array
    results = http.responseText.split(",");
    document.getElementById('username').value = results;
    
  }
}

function updateusername() {
var useridValue = document.getElementById("userid").value;
  http.open("GET", url + escape(useridValue), true);
  http.onreadystatechange = handleHttpResponse;
  http.send(null);	
	
}


function getHTTPObject() {
  var xmlhttp;
   /*@cc_on
  @if (@_jscript_version >= 5)
    try {
      xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
    } catch (e) {
	     try {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
      } catch (E) {
        xmlhttp = false;
      }
    }
    @else
  xmlhttp = false;
  @end @*/
  if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
	  try {
      xmlhttp = new XMLHttpRequest();
    } catch (e) {
      xmlhttp = false;
    }
  }
    return xmlhttp;
}
var http = getHTTPObject(); // We create the HTTP Object

</script>
