Question

This is my EnglishFonts.swf application that contains embedded fonts:

package
{
    import flash.display.Sprite;

    public class EnglishFonts extends Sprite implements IFontApplication
    {
        [Embed(
            source="../../assets/en/segoeprb.ttf",
            fontName="Segoe Print",
            unicodeRange="U+0048, U+0061, U+0073, U+006E, U+0074, U+003A, U+0030-0039"
        )]
        public var SegoePrintBold:Class;

        public function get fonts():Vector.<Class>
        {
            return Vector.<Class>([SegoePrintBold]);
        }
    }
}

In my Flex application, I load this EnglishFonts.swf through the Loader class and try to register the embedded font like this:

var fontsApplication:DisplayObject = loader.content;
var fonts:Vector.<Class> = fontsApplication['fonts'] as Vector.<Class>;
Font.registerFont(fonts[0]);

Font.registerFont() throws this error:

ArgumentError: Error #1508: The value specified for argument font is invalid.
    at flash.text::Font$/registerFont()

This error only occurs when I run my application in stand-alone Flash Player. It runs fine in the browser. I couldn’t figure out why this is.
