Dear List

I just noticed the following behaviour in R 2.3.1 Patched (2006-06-13
r38342) and confirmed similar behaviour in R 2.4.0 alpha (2006-09-18
r39383) & R 2.5.0 (2006-09-18 r39383) - which may actually be the same
thing?, that trying to plot the unicode character \u2030 (which should
be in a ? [per mille] sign) in an axis label leads to the following
error:

*** stack smashing detected ***: /home/gavin/R/R-devel/build/bin/exec/R
terminated
Aborted

The simplest, reproducible example I have tried is:

plot(1:10, ylab = "\u2030")

I can not reproduce this on my Debian GNU/Linux. I get something like "S 
for y label under 2.3.1 2006-06-01 and 2.5.0 2006-09-13 r39292 with the
following locale

[1] "LC_CTYPE=en_GB.UTF-8;LC_NUMERIC=C;LC_TIME=en_GB.UTF-8;
LC_COLLATE=en_GB.UTF-8;LC_MONETARY=en_GB.UTF-8;LC_MESSAGES=en_GB.UTF-8;
LC_PAPER=C;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=C;
LC_IDENTIFICATION=C"

It does not change if I set everything into en_GB.UTF-8. Is this valid 
unicode code?

Cheers for the follow up Gregor,

I was following advice given by Prof. Ripley in a posting on R-Help
about how to get the per mille character:

It should look like a "%" character but with two circles at the bottom.
