Special character problem as3 with php/xml

programming flash
1

Hi, I have a problem to see special characters (like "è,ò,ì…I see è), in flash when I load them from sql with php and xml.
Here my scripts:

AS3:

var myDomandaXML:XML = new XML();
var varDomande:URLRequest = new URLRequest(MyGlobal.LinkDomande);
varDomande.method = URLRequestMethod.POST;
var varLoaderDom:URLLoader = new URLLoader  ;
varLoaderDom.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoaderDom.addEventListener(Event.COMPLETE, processDATIDom);
varLoaderDom.load(varDomande);

function processDATIDom(e:Event):void
{
    var myDomandaXML = e.target.data;
    myDomandaXML = unescape(myDomandaXML);
    myDomandaXML = new XML(myDomandaXML);
    // I tried to use this too 
        //myDomandaXML.useCodePage=true;
    Domanda.text = myDomandaXML.DOMANDA;

PHP:

<?php
header("Content-Type: application/x-javascript; charset=ISO-8859-1");
#Include accesso a database
include_once "../config.php";
include "../query.php";

$query = mysql_query("SELECT * FROM domande WHERE ID = 1);
$row = mysql_fetch_array( $query );
        echo "<?xml version =\"1.0\" encoding =\"UTF-8\"?>
";
        echo "<TABELLA>
";
    echo "<DOMANDA>".$row['domanda']."</DOMANDA>
";
    echo "</TABELLA>
";
?>

I wrote in “row ‘domanda’” in database directly(just some example), collation is set to latin1_swedish_ci.

I tried to open php directly and I see characters correctly “è,ù” but in flash no…why? I’m going crazy…really…:s
