I think you need to play with the argument of pdf() function so that it supports a font with those characters. It uses postscript if I understand well. Graphic devices is not something I find easy.

You could also try other pdf devices

  • the cairo_pdf device from grDevices,
  • or Cairo::CairoPDF()
