Using Alpha Filters on Dynamic Textboxes

Very simple thing: You want to have a dynamic text box fade in and out with a simple alpha tween.

But it doesn't work. In order to add effects like the alpha tween to dynamic textboxes, you need to embed all the possible characters that might arise in that textbox. With textbox selected, the properties bar shows a button "Embed...". Click on that and you can choose which characters (Lowercase letters? Numbers? A-F?) to embed in the Flash file.

The more characters you embed, the larger the filesize of the final swf, so you really only want to embed those characters you think you'll need.
