You don't need to. pch="o" is the same as pch=111 (the ASCII

See ?points.

Well, pdftex is not a viewer and does not of itself process PDF
inclusions, but see ?pdf and the 'useDingbats' argument.
If you really think this is a bug in your LaTeX system, you should
report it. But you haven't shown us reproducible code, and similar
things have worked for me in the past.
