I'm not sure if this is related to the other Unicode/codec issue, but I'm trying out the pgf backend and I'm seeing what appears to be an issue with Unicode/codecs using matplotlib git master and Python 2.7 (Ubuntu 12.04):

The graph script is very basic:
import matplotlib as mpl
import matplotlib.pyplot as plt
fig = plt.figure()
sub = fig.add_subplot(1, 1, 1)
sub.plot([1, 2, 3], [2, 3, 4], label='Foo', markersize=2, marker='x')
sub.grid()
sub.set_axisbelow(True)
sub.legend(loc=2)
fig.savefig('t1.pgf', bbox_inches='tight')
I just built the latest git master with "python setup.py build" and used it directly from the build/ directory. Interestingly, the tests included with matplotlib do seem to generate graphs.
