RuntimeError In FT2Font with NISC18030.ttf #7305
Description
We're trying to fix the font in our MPL scripts to avoid PNG and PDF images changing depending on who produced it (Linux / Mac machines, different MPL versions).
So our idea was to find one font that everyone has and set that font.
How can I find out if I have 'Bitstream Vera Sans' (or some other font) available in my MPL install?
I tried this and got a RunTimeError.
Is this a bug or am I doing it wrong?

import matplotlib.font_manager
flist = matplotlib.font_manager.get_fontconfig_fonts()
names = [matplotlib.font_manager.FontProperties(fname=fname).get_name() for fname in flist]
print('Bitstream Vera Sans' in names)
