only support ascii codec now

[yyw794]

I am chinese, when I use in my jenkins, it cannot recognize chiese.
I have to hack cli.py like:
# encoding=utf8
import sys
is_py_v2 = True if sys.version[0] == '2' else False
if is_py_v2:
reload(sys)
sys.setdefaultencoding('utf8')

and, why not support python3?

Is this fixed with #31 ? Or should we keep this open if it's still an issue on Python 3?
