Font Embed question

My client seems to be seeing something different than me, and I have a feeling the font I used (Bitstream Vera Sans) is not what she is seeing.

I made one of my text boxes dynamic and embedded the font, choosing the alphas and the numerics. From an article I read that supposedly would mean the font is embedded for the whole file. Is that the case?

How do I make sure the font is embedded for the whole file? Do I have to embed every instance where I use that text? What I really need is some global way to specify that font is embedded…

Does it matter if they are in different scenes?
