In an elderly version of ``plotSymbols'' (now in the cwhmisc package) that
I had lying around, there was the example

In a Latin-1 encoding, which R gave up as default in 2.1.0.
You should just be able to use
plot(1:10,xlab="ΓΌ")
or failing that (and the mailer may trash that line)
plot(1:10,xlab="\u00fc")
When I execute this plot
(a) I get no x-axis label at all, and
(b) the plot ``freezes'' in that further plotting commands
(e.g. plot(runif(42))) produce no results. The plot window (X11)
remains as it was after the ``plot(1:10,xlab="\374")'' command.
No error message is given, but no new plot is produced.
If I do dev.off(), then normal plotting recommences. Can anyone explain
to me what is going on here? My session info is given below. I run R
from the command line, from a terminal window.
My guess is that this is your 'elderly' Mac OS X11 plotting system.
Does X11(type="Xlib") behave? If so, this suggests that the Mac OS X
implementation of cairo (supplied by Simon Urbanek) is not too robust
(which in a several ways we already know). On Linux I get warnings
(process:14674): Pango-WARNING **: Invalid UTF-8 string passed to
pango_layout_set_text()
and a 'broken char' symbol on the plot.
cheers,
