If the network/subnet/port/floating-ip created by horizon and named using Chinese,
it can not be shown by 'openstack network show <network-name>/openstack subnet show <subnet -name>/openstack port show <port-name>/openstack floating ip show <floating-ip-name>'

root@ctl01:~# openstack subnet show 测试子网
'ascii' codec can't encode characters in position 0-3: ordinal not in range(128)

If the network/subnet/port/floating-ip who set Chinese description,
it can not be deleted by 'openstack network delete <network-id>/openstack subnet delete <subnet -id>/openstack floating ip delete <floating-ip-id>'

root@ctl01:~# openstack network create test --description 测试

root@ctl01:~# openstack network delete test
