non-ascii

matplotlib-0.74 introduced unicode support in the *Agg and PS backends
-- see examples/unicode_demo.py

Strings with "embedded mathtext" like (r"test $\lambda$") are
currently not supported but this is listed on the goals page -
http://matplotlib.sourceforge.net/goals.html. You have to use
something like r"$\rm{test}\ \lambda$" currently. This is discussed
in the mathtext class documentation at http://matplotlib.sourceforge.net/matplotlib.mathtext.html

matplotlib0.81 introduced mathtext support using TeX proper, see
http://matplotlib.sourceforge.net/screenshots.html#tex_demo and
http://matplotlib.sourceforge.net/matplotlib.texmanager.html

Hope this helps!
