Public bug reported:

The issue is that execute() method formats stderr and stdout in an str-
type string into a unicode-type string (since it is doing _() which
would be unicode).When we do string formatting on that, it is doing an
implicit conversion from str-type to unicode-type strings using the
system locale. This is going to cause an error with Japanese and other
languages with non-ascii characters (stdout/stderr characters that are
not in that locale specific character set)

eg:
response = utils.execute(full_args, check_exit_code=False)\n File "/usr/lib/python2.7/site-packages/neutron/agent/linux/utils.py", line 120, in execute\n stderr=_stderr)\nUnicodeDecodeError: \'ascii\' codec can\'t decode byte 0xe6 in position 141: ordinal not in range(128)\n'
