[XeTeX] Diacritics in color

[Karljurgen Feuerherm]

Thanks, Khaled.

I realize the limitations etc.--just thought I'd note that these things
are in some measure possible, if one wishes to implement them (not that
one 'should', necessarily). In particular with regards to some recent
posts, I seem to remember that glyph sub-definition was not limited to
horizontal slices, either: one could define sub-bounding boxes of
whatever type. (And with WorldPad, the cursor could be placed within
glyphs, too, I think...)
