Arabric Font embed, and TLF use problem.

Hi all,

I meet a problem with embed the Arabric Font.

   [Embed(source="fonts/axtyoumn.TTF",fontFamily="AxtYoumna",embedAsCFF="true" ,unicodeRange="U+0000-U+1000")] 
   public const AxtYoumna:Class; 
   [Embed(source="fonts/AXTSIL__.TTF", fontFamily="AxtSImplifed",embedAsCFF="true",unicodeRange="U+0000-U+1000")] 
   public const AxtSImplifed:Class;   
   public function fonts()
    {
     Font.registerFont(AxtYoumna);
     Font.registerFont(AxtSImplifed);         
    }
   }

It succeed published into a .swf file. I load this file use

Font.enumerateFonts(false);

It shows the font I have embed, it seems embed succeed:

FontsName::: AxtYoumna ||||| FontsType::: embeddedCFF
FontsName::: AxtSImplifed ||||| FontsType::: embeddedCFF

Then I use AxtYoumna, AxtSImplifed for my textfield

   charFormat.fontFamily = ffont;
   charFormat.fontSize = fsize;
   charFormat.kerning = Kerning.ON;
   charFormat.fontWeight = fbold ? "bold" : "normal";
   //charFormat.fontWeight = "bold";
   charFormat.fontLookup = flash.text.engine.FontLookup.EMBEDDED_CFF;
   charFormat.renderingMode = flash.text.engine.RenderingMode.CFF; 
   charFormat.cffHinting = flash.text.engine.CFFHinting.NONE;

The Text still not render correctly. 

My builder is FLex 3, flash player 10, and Flex SDK 4.0.0.10485

But if I use the font Arial/Arabic Transparent/Traditional Arabric, it works.

I use AXtYOumna/AXtadvertising/AXtSImplified Light /AXtGihaneLightItalic /AXtYouSra/AXTTraditionalLight , it not works.

I can use these font in Photoshop CS4 middleeast version to show arabic succeefully.

Please help me.!
