Bug summary
I use Python 3 and save data to files with Unicode names. Then I want to save figures with the same names.
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 5)
y = np.sin(x)
fig = plt.figure()
plt.plot(x,y)
name = 'ωω'
plt.savefig(name + '.eps', format='eps', bbox_inches='tight')Actual outcome
