Arabic vocalization diacritics are not rendered correctly using Adobe Arabic as Embedded Font

Hello,

this is my whole code:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"

               minWidth="1024" minHeight="768"
               creationComplete="init()"
               xmlns:controls="flashx.textLayout.controls.*">
    <s:layout >
        <s:VerticalLayout/>
    </s:layout>
   
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
       
        <s:HTTPService id="httpServiceObj" url="TopFirst.txt" result="handleResult(event)"
                       fault="handleFault(event)" 
                       resultFormat="text"/>

    <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";

          @font-face
        {
            src:url("trado.ttf");
            fontFamily: ArabicFont;
            fontWeight: normal;
            font-style:normal;
            advancedAntiAliasing: true;
           
        }

            private function init():void{
                httpServiceObj.send();
            }
            [Bindable]
            private var _str:String;
            private function handleResult(event:ResultEvent):void{
                _str    =    event.result as String;       
            }
           
            private function handleFault(event:FaultEvent):void{
                Alert.show("fault is = " + event.fault.faultString);
            }
               
           
        ]]>
    </fx:Script>
   

    <s:TextArea text="{_str}"  width="100%"
                height="100%"
                fontSize="50"
                />
       
   
</s:Application>

As you can see from the code, I am not given any font to the TextArea , even  after giving the font which I have embeded ,out is the same.

Where I am going wrong..

This is true for the version of Arial that ships with Vista.  The XP version of Arial has the non-zero-width diacritic problem, unfortunately.

That's a great question and I don't know the answer. Maybe some Arabic fonts work properly and others don't? Hopefully someone on the TLF team will provide the answer.
