[R] 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).

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.:

pdf("~/tmp/test_per_mille.pdf", paper = "a4", family = "URWBookman") plot(1:10, ylab = "\u2030")

But all I get here is a period or a dot-like symbol.

I've tried this in R 2.4.0 alpha [4] and R 2.5.0 to be [4] as my self-compiled R 2.3.1-patched dies when plotting Unicode characters (fixed in 2.4.0 alpha and above [3])

Can anyone point me in the right direction to get this working?
