Yes, it's X11, with locale "C". It doesn't happen with postscript (I haven't tried anything else). I had tried on 3 different machines other than my desktop, but all remotely.

I'm not really sure what I'm looking for, but everything I get seems to be 'fontspecific': deepayan $ xlsfonts | grep adobe-symbol-medium -adobe-symbol-medium-r-normal--0-0-0-0-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--0-0-100-100-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--0-0-75-75-p-0-adobe-fontspecific -adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--10-100-75-75-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--11-80-100-100-p-61-adobe-fontspecific -adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific -adobe-symbol-medium-r-normal--12-120-75-75-p-74-adobe-fontspecific -adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-100-100-100-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific -adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific -adobe-symbol-medium-r-normal--17-120-100-100-p-95-adobe-fontspecific -adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--18-180-75-75-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--20-140-100-100-p-107-adobe-fontspecific -adobe-symbol-medium-r-normal--24-240-75-75-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--24-240-75-75-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--25-180-100-100-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--25-180-100-100-p-142-adobe-fontspecific -adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific -adobe-symbol-medium-r-normal--34-240-100-100-p-191-adobe-fontspecific -adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific -adobe-symbol-medium-r-normal--8-80-75-75-p-51-adobe-fontspecific deepayan $ -Deepayan ______________________________________________ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
