How to draw a per mille symbol?

Dear list, Following advice posted to this list a while back by Prof Ripley [1], I have been trying to draw a per mille character [2] in an axis label. This should give the correct character: plot(1:10, ylab = "\u2030") but all I get is '"S'. I'm running linux (FC5) and have fonts installed that have the correct character (viewed in the Gnome character map at least).
On what device? If X11, this is almost always a font selection issue. Unicode support in X11 fonts is a complex issue that seems to vary with every minor update.
I have also tried plotting to a pdf device with a font family that the character map tool shows I have a per mille glyph for, e.g.:
What does character map have to do with postscript fonts?
pdf("~/tmp/test_per_mille.pdf", paper = "a4", family = "URWBookman")
plot(1:10, ylab = "\u2030")
dev.off()
But all I get here is a period or a dot-like symbol.
But see the article in R-news 2006-2 about this. All we can do for PDF is to use an appropriate 8-bit font map, or a CJK font. It seems that e.g. encoding="CP1251" works, even for Helvetica.
