Hi Alfredo Deza

  I see your below PR in ceph

     PR 23289 "ceph-volume ensure encoded bytes are always used"

  I meet with one problem when using ceph-deploy to deploy ceph cluster.

  During running ceph-volume command to create OSD through ceph-deploy, it always hit below problem:

     nstcc1@nstcloudcc1:deploy$ PYTHONIOENCODING=UTF8 ceph-deploy osd create --data /dev/sdc nstcloudcc1

     [nstcloudcc1][WARNIN]  stderr: purged osd.0

     [nstcloudcc1][WARNIN] -->  UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 132: ordinal not in range(128)

     [nstcloudcc1][ERROR ] RuntimeError: command returned non-zero exit status: 1

     [ceph_deploy.osd][ERROR ] Failed to execute command: /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/sdc

     [ceph_deploy][ERROR ] GenericError: Failed to create 1 OSDs

  Do you know how to solve the problem?

  Below is the deploy host environment:
