How to display chinese labels?

I am trying to generate and display a graph with chinese labels. In matplotlib we can set “plt.rcParams” to support it, so how can I set system form when using igraph?

MacOS 10.14.6
cairocffi 1.1.0
python-igraph 0.8.2

This is a known issue with the fonts Cairo uses. The workaround, as far as I known, is either to use a Cairo context with a different font, or two write out an SVG file and change the font in the SVG output.
