What names should I use for f_ij and f_f_ij ligatures to get them to appear in automatically generated feature code? I’ve tried f_ij.loclNLD.liga and f_ij.liga.loclNLD and neither works.
I am afraid you cannot automate that one because some parts of the ligature have a suffix and some don’t. f_i_j.loclNLD.liga is my best guess for a fitting glyph name.
If you are really using the (deprecated) ij glyph, f_ij.liga would suffice.
