See ?pdf particularly the Notes section, which has:
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.
