After installing matplotlib (on Windows, via miniconda) to a non-ascii path, running
python -c "from matplotlib import pyplot as plt; plt.xlabel('$x$'); plt.show()"
fails with a long traceback that ends with
File "C:/non/ascii/path/to/matplotlib/mathtext.py", line 584, in _get_font
font = FT2Font(str(basename))
RuntimeError: Could not open facefile C:/non/ascii/path/to/matplotlib/mpl-data/fonts/ttf/Vera.ttf; Cannot_Open_Resource
Note that this is specific to Windows (I wasn't able to reproduce the issue by creating a virtualenv on Linux) and to non-ascii paths (changing the path solved the issue).
