[flexcoders] Embedding Flash font

[candysmate]

I have created a Flash 8 swf as per: 
http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Book_Parts&file=fonts_070_12.html
containing the Windings font.
In my external css files I have :

.myWingdingsStyle {
        font-Family: Wingdings;
        font-Size: 16;
        font-Color: #FF0000;
}       

and in my MXML  script section I have:

[Embed(source='/assets/wingdings.swf', 
            fontName='Wingdings'
        )] 
        private static var plainFont:Class;

Within my label component I have:

<mx:Label x="324" y="129" htmlText="&#251;" textAlign="center"
id="percentageProblem" visible="true" styleName="myWingdingsStyle"/>

This sgould give me the ballot box style cross, but I only get a
capital U witb a reflex accent over it. Where am I falling down?
