Subject: use encode('utf8') instead of str()
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=c98cf2d8;p=openstack-build%2Fcinder-build.git

use encode('utf8') instead of str()

It is not clear for converting a unicode to string by using str().
Instead we should use var.encode('utf8') to do this.
