Thanks for your help.
The output of > pdfFonts()$serif$metrics and > pdfFonts()$mono$metrics is what you mention.
Unfortunately I have no duplicated fonts, so the problem is not there...

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:
 "Times-Roman.afm" "Times-Bold.afm" "Times-Italic.afm"
 "Times-BoldItalic.afm" "Symbol.afm"
 "Courier.afm" "Courier-Bold.afm"
 "Courier-Oblique.afm" "Courier-BoldOblique.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.
(This is documented in ?quartz.)

A full test would be:
pdf(); plot(1,1, main=expression(delta)); dev.off()
