R help - Jun 2009 - symbols duplicated in plot output

Dear list,

I'm manually editing a large collection of pdf files that I produced with R
in Adobe Illustrator. In doing so, I've had the surprise to see symbols
duplicated on top each other. The following code illustrates this,

pdf()
plot(1, xlab=expression(mu))
dev.off()

If I open this pdf in Illustrator CS4, there are two "mu" on top of
each
other, giving it a somewhat bold aspect. Other characters not from the
symbol font are just output in one version. I'm guessing this may be very
much dependent on my config, which is,

sessionInfo()
R version 2.9.0 (2009-04-17)
i386-apple-darwin9.6.0

locale:
en_GB.UTF-8/en_GB.UTF-8/C/C/en_GB.UTF-8/en_GB.UTF-8

attached base packages:
[1] grid      stats     graphics  grDevices utils     datasets  methods
[8] base

Thanks for any advice, (and apologies if there was an obvious source of
information that I failed to check).

I was able to reproduce this on Windows. When you open the file with
notepad, you will notice duplicate lines just above the endstream:

BT
0.000 0.000 0.000 rg
/F6 1 Tf 12.00 0.00 -0.00 12.00 262.94 18.52 Tm (m) Tj
ET

When you remove these, problem is gone. I would consider this a bug, but do
not dare to call it one.
