I want to add additional ligatures to an OpenType typeface i'm developing. I've included ff fi fl ffi ffl ft st and want to add ffb ffh ffi ffk ffl fft fh fj fk fl ft sp fb fh fk. Can anyone advise on what Unicode Names I need to use. I was looking at the PUA values which Warnock Pro uses (E032, E033) but Adobe recommends against this as it can lead to incorrect funtionality. Any help would be really appreciated.
