Designate DNS – create TLD using valid Unicode string

[Arkady Shtempler]

Scenario:
Try to create a new TLD using Unicode string, for example: “例え”

Actual Result:
API fails with:
Details: {'code': 400, 'type': 'invalid_object', 'message': 'Provided object is not valid. Got a ValueError error with message \u4f8b\u3048 is not an TLD', 'request_id': 'req-fa7cb43e-a6e9-41f2-b878-1ced6a853a2a'}

Expected Result:
Should pass

Notes:
1) There is an tempest patch could be used to reproduce the scenario:

Not a neutron bug. I changed it to designate.
