Keystone doesn't like UTF-8 characters

Issue

• We are having trouble when integrating Keystone with our LDAP, which uses non-ASCII characters in multiple fields. In this case, the error is triggered when the Keystone client output is not a terminal:

Apr 11 10:33:32 localhost os-collect-config: #033[1;31mError: Could not prefetch keystone_user provider 'openstack': Execution of '/usr/bin/openstack user list --quiet --format csv --long' returned 1: ERROR: openstack 'ascii' codec can't encode character u'\xd1' in position 24: ordinal not in range(128)

• This can be reproduced by hand by running the following command from a terminal:

[root@hostname01 ~]# openstack --os-token redacted --os-url http://10.10.10.10:35357/v2.0/ user list --quiet --format csv --long 2>&1 | grep .
ERROR: openstack 'ascii' codec can't encode character u'\xd1' in position 24: ordinal not in range(128)

• One workaround is to remove the "| grep ."

[root@hostname01 ~]# openstack --os-token redacted --os-url http://10.10.10.10:35357/v2.0/ user list --quiet --format csv --long

• Another workaround is to patch /usr/lib/python2.7/site-packages/cliff/formatters/commaseparated.py
