Font Fallback in Agg

It is now possible to specify a list of fonts families and the Agg renderer

well try them in order to locate a required glyph.

.. plot::

:alt: The phrase "There are 几个汉字 in between!" rendered in various fonts.

:include-source: True

import matplotlib.pyplot as plt

text = "There are 几个汉字 in between!"

plt.rcParams["font.size"] = 20

fig = plt.figure(figsize=(4.75, 1.85))

fig.text(0.05, 0.85, text, family=["WenQuanYi Zen Hei"])

fig.text(0.05, 0.65, text, family=["Noto Sans CJK JP"])

fig.text(0.05, 0.45, text, family=["DejaVu Sans", "Noto Sans CJK JP"])

fig.text(0.05, 0.25, text, family=["DejaVu Sans", "WenQuanYi Zen Hei"])

plt.show()

This currently only works with the Agg backend, but support for the vector

backends is planned for mpl3.7.
