(Ill give it a try, but more expertise than I have may be needed) Works fine for me (on OS X).
Take a look at ?pdf . I believe the font family in use (Helvetica is the default) needs to have the (Adobe) symbol font as font 5. What family are you using? To see what families are available, use: names(grDevices::pdfFonts()) Another possibility is that you are using the wrong encoding. Unfortunately, this is beyond my ability to help you with, but perhaps reading the Help on the encoding argument and related links might get you the necessary info.
