funny bug with greek letters

#1

Hi list,
when I do:
hist(randn(100)); xlabel('$\gamma$')
things work as expected.
However, if I try:
hist(randn(100)); xlabel('$\beta$')
then either I get an error, or I get the label "eta" under the plot.
Other letters seem to trigger this: tau, alpha, rho, maybe others.
This problems wether text.usetex is set to True or not (in matplolibrc file).

Version: 0.98.5.2 (Ubuntu Jaunty, ipython 0.9.1 shell).

Has anyone had the same problem, and is there any fix?
Sorry if this has been reported before, I tried to find it, but
nothing came out.

Thanks in advance

In [162]: print "$\beta$"
eta$

In [163]: print r"$\beta$"
$\beta$

use the raw sting for math expression.

thanks a lot! I did not know about raw strings, sorry, even Python has
its black corners, I guess.
funny \gamma works, though.
On a related note, usetex=True is fancy, but produce much bigger eps
files for me, so I stick with the standard mathtex rendering.
Thanks again
Nicolas
