Many thanks for your reply, Hans.
In order to modify the fonts, it would be helpful to have a function
that can substract two glyph widths of a given font, such as:
function document.hanging_diacritics(char_one, char_two)
return (char_one.glyphwidth - char_two.glyphwidth)
end
I don’t have any idea about how to do it. This way I don’t have to
calculate the value for each glyph feature and I can simply add the
values to the font.
BTW, what kind of specifications you think can be constructed for the
lfbd feature (sorry, but I don’t get it).
Many thanks for your help,
Pablo
