Yes, the figure is produced in R.  I want to include figures like that 
in LaTeX documents.  When I do, I see the same font problem, but I 
figured it was simpler just to give the figure itself.

R doesn't use GhostScript, it has its own pdf driver code.  However, I 
see in the documentation for that:

"On some systems the default plotting character pch = 1 is displayed in 
some PDF viewers incorrectly as a "q" character. (These seem to be 
viewers based on the poppler PDF rendering library). This may be due to 
incorrect or incomplete mapping of font names to those used by the 
system. Adding the following lines to ‘~/.fonts.conf’ or 
‘/etc/fonts/local.conf’ may circumvent this problem.

<alias binding="same">

(You can see the full text at


in the "Note" section.)

It gives some workarounds that generate the figure without using the 
Dingbats font; they work.

Is there a way to do the equivalent of what was recommended above in 
TeXworks?  I don't know where to look for a .fonts.conf file or 
/etc/fonts/local.conf on Windows.
