qpdf's don't work for me. But I added the `-P-y -PU' into the actual git-groffer in mode `--pdf'. So the suitable code will be called automatically. I could not do that for the `groffer ' mode `--pdf2', which uses `groff' mode `ps' and generates `pdf' with `ps2pdf'. There the ligature error still exists. As the pdf-mode of `groff' improved, `groffer --pdf2' seems to be no longer necessary. How about appending the `-P-y -PU' in pdf-mode also for the new coming `grog'? Bernd Warken
