AJAX and special characters

[Yashin_S]

hi everyone.

Am trying to get some data (in french) from a database, but the special characters like "é" are getting replaced by question marks. I have been able to find a way in mozilla using

xmlHttp.overrideMimeType('text/xml; charset=iso-8859-1');

but it is not working in IE7 and IE6.

here are the codes :

function showArticles(rubrique)
		{ 
			xmlHttp=GetXmlHttpObject();
			if (xmlHttp==null)
			  {
			  alert ("Your browser does not support AJAX!");
			  return;
			  } 
			var url="displayTable.php";
			url=url+"?r_id="+rubrique;
			xmlHttp.onreadystatechange=stateChanged;
			xmlHttp.open("GET",url,true);
			xmlHttp.send(null);
		}



function stateChanged() 
		{ 
			
			if (xmlHttp.readyState==4)
			{ 
				document.getElementById("dynamicTable").innerHTML=xmlHttp.responseText;
			}
		
		}




function GetXmlHttpObject()
		{
		var xmlHttp=null;
		try
		  {
		  // Firefox, Opera 8.0+, Safari
		  xmlHttp=new XMLHttpRequest();
		  xmlHttp.overrideMimeType('text/xml; charset=iso-8859-1'); //NO CHARACTER PROBLEM IN MOZILLA
		  }
		catch (e)
		  {
		  // Internet Explorer
		  try
		    {
		    xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
			//xmlHttp.overrideMimeType('text/xml; charset=iso-8859-1'); // THIS DOES NOT WORK, I"VE COMMENTED IT
		    }
		  catch (e)
		    {
		    xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
		    }
		  }
		return xmlHttp;
		}
