iso-8859-2 text in titles and labels

Hello,

I have the following script and in matplotlib 0.87.5 (debian sid) and text is not
correctly displayed, whereas in matplotlib 0.82-1 it was ok. See attached
pictures.

#!/usr/bin/python
# -*- coding: iso-8859-2 -*-
from pylab import *

ab = unicode('�����','iso-8859-2')

plot([1, 3, 4],[1, 4, 2])
xlabel(ab)
show()

I found that the problem occurs when I have GTKAgg, WXAgg or PS backends set in
matplotlibrc file and matplotlib displays fonts properly when using
GTK, WX as backend. So I guess that it must be something wrong with recent
antigrain or preparing text for agg rendering.
