Here is the solutions for our problem. The reason for this behavior was the 
next code
in the settings.py file:

import sys
reload(sys)
sys.setdefaultencoding("utf8") 

Removing this solves the problem, but now we have to add 
# -*- coding: utf-8 -*-
to every file where we have Unicode string.

Hope this will help others too.
