The outline fonts I'm finding define the black areas and their centers are empty, leaving the background colors to come through. I need a black outline with a white opaque center that overlays the background, preferably in the Arial family (or similar). Do such two-tone fonts exist?
Current generation of fonts can only have one color. Older font technologies could do colored fonts. Also the next generation technology can do so, but its not entirely rolled out yet (but is basically same as earlier with xml tags).
The way you circumvented this is to have your editor stroke, or dropshadow the stroke. Or overlay two text on top one white and one outline.
