embedFonts question

Let’s say I make a textbox on frame one of my movie and embed a font called “Crazyface-Bold” into that textbox.

Can I create an empty text field at runtime and assign it a font value of “Crazyface-Bold”?

Would that work? The reason I ask is that I only need certain ranges and I don’t want to embed a whole font into the library. Creating text fields on the fly is a must though.
