I build the Accents ToolBox [ATB] for quick, easy and automatic handeling the accents.
It relies heavily on RoboFab, as most of my scripting I do.
The glyphConstructions that came with RoboFab were a good start but I soon realized that the anchors ‘top’ and ‘bottom’ where too common. Some accents needed a specific anchor. So for my ATB I rewrote the glyphConstructions.
Part of the ATB is Accents Overlay. An observer drawing the accents in the glyphView. I think it’s very handy for the positioning of the anchors. AccentsOverlay can also generate accented glyphs. But BatchAccents does it too, and quicker.
