Description
Saving vector graphic figures with certain characters in LaTeX will fail. Here I tried to use the \textmu character. Could it be related to #8068?
Code for reproduction
Here I'm saving to PostScript. It gives an error that I think is the most informative and points to some problems with ghostscript. Outputs for SVG and PDF below.
import matplotlib
matplotlib.rcParams['text.usetex'] = True
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_ylabel(r'\textmu')
plt.savefig('fig.ps')Output - PS

For PDF it's nearly identical; the last line reads:
KeyError: b'tcss1000'
In case of PS and SVG, no file is produced. In case of PDF, a corrupted file results. Saving to raster formats and inline previews in jupyter notebook work fine.
