Does the workaround pointed out later in the thread you're
responding to (from the last paragraph of a very long 'Note'
section of ?pdf) help?
If not it might be worth continuing this thread on r-devel .
It does seem that there are two (related?) issues, one with
pch=1 and the other with Symbol (???) fonts ...
although it's also not clear whether this is exactly
the same issue, or a related/similar one.
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
