I really do not understand these conversions.
I've just found a bug with this patch (sorry it is already applied).

When running the view command with python2 from a shell script there
is an error because of a non-ascii character:

  File "pwclient", line 768, in main
    print(unicode(s))
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0142'
in position 468: ordinal not in range(128)

This error does not happen with python3.

Shell script to reproduce the error with a DPDK patch:

#! /bin/sh -e
python2 pwclient view 17892

.pwclientrc:
[options]

What is the magical invocation to make it work with Python 2 and 3?
