You may encounter several errors while Running Python Scripts that work with terminal and translations:

1. Error getting LANG from environ:
   

     File "/usr/lib/python2.7/dist-packages/gitinspector/localization.py", line 48, in init
       os.environ['LANG'] = lang[0]
     File "/usr/lib/python2.7/os.py", line 471, in __setitem__
       putenv(key, item)
   TypeError: must be string, not None
   

2. Error getting sys.stdin.encoding

       argv.append(arg.decode(sys.stdin.encoding, "replace"))
   TypeError: decode() argument 1 must be string, not None
   

To solve these problems you only need to specify several environ variables when running your python scripts:

export LOCALE="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
export LANG="en_US.UTF-8"
export PYTHONIOENCODING='utf-8'
