When I right-click on a Filter (for example Mac Roman) and try to generate the missing glyphs, by selecting all or some of the listed glyph names nothing happens.
Doing the same thing on the default classifications(f.ex. number–>oldstyle figures) works perfectly
Fixed it.
Just uploaded a new beta version. Can you try it?
Better. But still, for some strange reason there are some characters I cannot generate at all, from any filter or classification:
Iacute
Icircumflex
Imacron
Iogonek
Idieresis
Igrave
all the others work without problem
I actually cannot even add those from Font–>Add glyphs!
Solved it by copy/pasting from another font
