Probably you need a unicode font-set that contain all the characters for
those alphabets. You can look at this example to see a simple unicode
demonstration example.

Make sure you are using the right font in your matplotlib.

You have to adjust your label to get it seen. You may try with:
xlab = plt.xlabel("my x-axes label")
xlab.set_position((0.2, 0.1))

Two ways I can think of are: annotate and text functions of pyplot api.

Let me know if these work fine for you.
