You mean as in

?

This works fine for me on OpenSUSE 10.2, so I don't think the issue is
in R. More likely, this has to do with X11 fonts (Unicode is handled via
a rather complicated mechanism involving virtual fonts). Postscript/PDF
is a bit more difficult. See ?postscript and the reference to
Murrell+Ripley's R News article inside.

The correct incantation seems to be

postscript(font="URWHelvetica", encoding="ISOLatin7")
plot(0,main=tolower("\u104\u116\u0118\u012e\u0172\u016a\u010c\u0160\u017d"))
dev.off()
