Need help with SaveFontTexture fonts

I've created a font texture with the SaveFontTexture script on the community wiki, and one of the first things I wanted to do was add an outline to the font in Photoshop. So after adding an outside stroke to the font and coloring it a bit, I noticed when I loaded it back in Unity that everything that wasn't part of the original font is not showing. (ie: the outline)

Is there a way to get the font to recognize the outline I added?
