Hi,

      I would like to use the embed font for the only Numberic and English 
letter but use the default for different country language (eg. Chinese). I 
found that i cannot do that in the following code. Can some expert give me 
advice on it?

<?xml version="1.0"?>
<!-- fonts/EmbeddedFontCharacterRange.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";>
  <mx:Style>
     @font-face {
        src:url("test.ttf");
        fontFamily: myFontFamily;

        unicodeRange:
           U+0041-U+005A, /* Upper-Case [A..Z] */
           U+0061-U+007A, /* Lower-Case a-z */
           U+0030-U+0039, /* Numbers [0..9] */
           U+002E-U+002E; /* Period [.] */        
        
     }


  </mx:Style>

  <mx:Panel title="Embedded Font Character Range">
        <mx:TextArea width="400" height="150" text="abcdTest&#28204;&#35430;" 
fontFamily="myFontFamily"/>
