Is there a sensible way (e.g. a script) to list all kernings groups that are present in the file? I don‘t mean the individual glyphs to belong to a group (e.g. A, Aacute, Abreve that belong to the A kerning group), but rather list the defined groups like so:
LSB: A, H, J, O, …
RSB: A, B, C, E, F, …
I am specifically asking for a list that I can copy and use programatically in my own script—I am familiar with the List View that allows to sort glyphs by their kerning group.
