Thanks, Rafael, for figuring that out. That definitely shows the MS fonts that are freely downloadable for Linux are much less complete in math symbols than the free fonts. > > I hope that this exercise will convince you that my claim about the > incompleteness of the MS fonts is correct. Yes, for the freely downloadable ones that are available for Linux. BTW, getting back to Arjen's original question, what matters here for PLplot windows users is not what MS fonts have been made available (by a nice licensing accident) to Linux users, but what is available by default on their windows systems. I would be surprised if the default MS fonts available on windows systems did not include math symbols. Of course, if there is some trouble with math symbol coverage for the MS default fonts or additional math symbol fonts cost a big license fee, the free fonts with complete math symbol coverage are available as well to MS users. Arjen may have to experiment to come up with a good default combination, but that should be easy to do once the #(nnnn) access method works for non-Hershey fonts. The MS defaults we have now for plfreetype.c might work fine for windows since they worked for Andrew (Roach) on his djgpp/DOS system. > > Besides, why do you keep supporting Bill Gates? Are you changing sides? :-) Rafael, through our private contacts you know I have never experienced windows and have no intentions of burdening my life learning a new OS so this particular joke was fine once but has become somewhat stale through repetition. For the others here, I jumped directly from Unix to Linux with no stopovers in the windows world. I cannot claim any great virtue because of this. Instead, I was just lucky that Linux fit my scientific computing needs so well even back in 1996 and of course ever since. Perhaps because of my zero experience with windows, I am more tolerant of windows and Bill Gates then Rafael seems to be. Anyhow, I am happy to encourage Arjen to make PLplot work well on windows including good font access, and I think Rafael has the same attitude. Alan __________________________ Alan W.
