Bug summary
When I use a very minimal example with the PGF backend I get an LaTeX error.
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
plt.rcParams.update({"pgf.texsystem": "pdflatex"})
x = np.linspace(-0.5, 0.5, 200)
fig, ax = plt.subplots()
ax.plot(x, x)
plt.savefig('out.pgf')Actual outcome
ValueError: Error processing '−0.4'
LaTeX Output:
! Package inputenc Error: Unicode character − (U+2212)
(inputenc) not set up for use with LaTeX.
See the inputenc package documentation for explanation.
Type H <return> for immediate help.
...
<*> ...ze{10.000000}{12.000000}\selectfont −0.4}
