Bug report

Bug summary

I cannot write Japanese comments on matplotlib's graphs.

Code for reproduction

import matplotlib.pyplot as plt
data_a = [1, 2, 3, 4, 5]
data_b = [1, 4, 9, 16, 25]
plt.title('V_DS-I_D特性')
plt.scatter(data_a, data_b)
plt.show()

Actual outcome

The part written in Japanese appears as weird rectangles.

Matplotlib version

That is because the default font (DejaVu Sans) does not have CJKV [chinese japanese korean vietnamese] glyphs. Matplotlib 3.1+ (#12759) prints a warning: Requested glyph (\N{CJK UNIFIED IDEOGRAPH-7279}) missing from current font.

See #12597 for essentially the same issue.
