Hi Marc,

 

If you can provide some examples, I would like to look into this difference. I think I need a mom source file which shows the difference and a copy of the groff font file and associated .pfa font which has the problem. It may also help if you can produce the pdfs one from pdfmom and one from pdfroff (although pdfmom -T ps should be using pdfroff).

 

Cheers
