That's not very informative, since the actual fonts that are going to be used are inside the 'serif', "sans", and "mono" families. Try this instead: > pdfFonts()$serif$metrics [1] "Times-Roman.afm" "Times-Bold.afm" "Times-Italic.afm" [4] "Times-BoldItalic.afm" "Symbol.afm" > pdfFonts()$mono$metrics [1] "Courier.afm" "Courier-Bold.afm" [3] "Courier-Oblique.afm" "Courier-BoldOblique.afm" [5] "Symbol.afm" Notice the the fifth item in both is Symbol. Which may also not be very useful either since for reasons that I have never been able to fathom, the fonts sometimes get messed up on a Mac and the way to detect and correct the problem is to use Font Book.app which I think you will find in either ~/Applications or ~/Applications/Utilities. The symptom: ... you find a font type in Font Book that has duplicate entries. Delete the corrupted one and you may find your Symbols will reappear.
