Embedding Bold and Italic fonts in a dynamic textfield, Impossible?

Hi. I’ve been trying to find a solution to this since Flash got rid of it’s ‘Faux bold’ option in CS3.

Using a basic Arial font. I have embedded, the Regular, Bold and Italic versions of the Arial font in my lIbrary.

Here is my code:

exampleTF.htmlText = "regular or <b>bold</b> or <i>italic</i> font."; 

I have attached an Fla, CS5

If anyone has a solution to this I would be grateful
