Bug report
Bug summary
Using tex (rcParams["text.usetex"] = True) results in an error because of a font name not being valid in current master. Works fine with matplotlib 2.2.3.
Code for reproduction
import matplotlib.pyplot as plt
plt.rcParams["text.usetex"] = True
plt.plot([1,2,3])
plt.show()
Actual outcome
File "d:\***\matplotlib\lib\matplotlib\dviread.py", line 736, in __init__
with open(filename, 'rb') as file:
OSError: [Errno 22] Invalid argument: 'D:/Programme/Office/MiKTeX/fonts/tfm/public/cm/cmr10.tfm\r'
I would suspect the \r simply does not belong at the end of the string.
