I downloaded anaconda (the python2.7 version) but have troubles using it. I tried to trash it and install anaconda again but the problem is persistent:

when i try to use matplotlib with a simple code:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()

It works when I use a text editor (sublime text) but not when I use ipython or jupyter notebook. I get the following error (using jupyter ipython notebook or ipython) 

    ---------------------------------------------------------------------------

ValueError: unknown locale: UTF-8

any help would be greatly appreciated

when i type locale into the terminal i get: 

LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=
