Embedding font in Flex 4 (spark components)

Embedding fonts in Flex 3 can be achived by

@font-face {
 src : url("comic.TTF");
 fontFamily : comic;
 }

But this will not work in flex 4. We need to add one more property ‘cff’ and setting it to true.

 @font-face {

 fontFamily : comic;
 cff : true;
 }
 .myStyle {
 font-family : comic;
 font-size : 24;
 }
 </fx:Style>
