One of the things i love about Flash (and man, there are so few things) is that you can embed a range of Unicode characters of a specific font into your application. A range is basically a set of characters that exists in your desired font (ie Latin characters). For more info on Unicode characters and ranges, go here.

So, now, how does one embed a font into Flex?

Well, it’s actually quite simple. Inside of the <Style> tag or in an external .css file, you can embed a font using the following syntax:

@font-face
{
      src:url("../assets/MyriadWebPro.ttf"); /* A .ttf inside your project */
      fontFamily: myFontFamily;
}

or using an installed font:

@font-face
{
    fontFamily: "Lucida Sans";
    src: local("Lucida Sans");
}

The following syntax illustrates how to embed only certain unicode ranges of your font:

@font-face
{
    src:url("../assets/MyriadWebPro.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 [.] */
}

Now how cool is that?! Flex rocks!
