[R] set pdf.options() encoding to UTF-8

[Liviu Andronic]

Dear all
Can anyone point to a list of valid pdf.options() encodings? I checked
?pdf and ?postscript, but they do not quite answer my questions. I
would like to try UTF-8 instead of the default "ISOLatin1.enc" for
Sweave plots (I have issues with Greek characters in labels).
Thank you
Liviu
