Below operations are getting failed with (HTTP 500) in case unicode 4 byte characters are used:
1. backup-create Creates a volume backup.
2. cgsnapshot-create Creates a cgsnapshot.
3. consisgroup-create Creates a consistency group.
4. create Creates a volume.
5. encryption-type-create Creates encryption-type
6. qos-create Creates a qos specs.
7. snapshot-create Creates a snapshot.
8. type-create Creates a volume type.
9. update/edit of entities mentioned in step1-8 update/edit name.
( is already taken care)
Update/Edit volume + Point number 4 and point number 7 are taken care in https://bugs.launchpad.net/cinder/+bug/1393871
Same fix can be used to facilitate these APIs as well to handle 4 byte unicode characters in synced manner.

This problem for snapshot and volumes are taken care in https:/
Same fix can be used to facilitate other APIs to handle unicode characters in synced manner.
I will submit patch once fix for https:/
