Second, it's generally better (unless it's really personal or highly technical) to keep the discussion within the mailing list, since then other people can also contribute; I am far from an expert. Thus I have brought the discussion back to the list. > > These two problems I noticed, too. > > About the problem with misaligned brackets I wrote, I think, before, > > And I therefore Mentioned where the problem-'may be.

As far as I can tell the system is simply old and the various parts of it have not been really mantained. It has also never been put together so that the letter coverage would be good. Further there is a licencing issue on (I think) Lucida fonts (which can be only used on p9 but not on p9p), some of it, however, was replaced by another set. (I don't know much more, search the archive, or perhaps somebody else will tell more.) I believe that majority of font problems would now be solved differently; note that heirloom troff (contrary to groff) can read opentype. > > Note thatthere are so bugs in the p9 version wrt the p9p > > Version.
