See ?pdf and note the following in the Note section:
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.
<fontconfig>
<alias binding="same">
<family>ZapfDingbats</family>
<accept><family>Dingbats</family></accept>
</alias>
</fontconfig>
Some further workarounds for problems with symbol fonts on viewers using
?fontconfig? are given in the ?Cairo Fonts? section of the help for X11.
