unicode text when using savefig() in matplotlib

Question

I am new to matplotlib and trying to plot a 2D/3D chart with non-ASCII texts in it, I am able to use show() to plot on screen:

plt.text(X, Y, str(text[i].decode('utf-8')) )
plt.show()

However when I try to save the figure to a file with savefig(), all texts become little squares []

I am sure it is a font related problem but I can't see to figure out how to fix this.

I am on a Mac OSX 10.10.5, if that matters.

Thanks, I googled that question but I try the suggested fonts without luck. — Wei

Yes, it depends very much on your unicode characters and the character map of the font. E.g. Arial won't have any glyphs for Chinese characters. — Bernhard

finally solved it by using:

fontpath = '/Library/Fonts/华文细黑.ttf'
properties = font_manager.FontProperties(fname=fontpath)
matplotlib.rcParams['font.family'] = properties.get_name()
