Can't create orgs with russian names

After creating first org with russian name it's not possible to create another one, because of errorr: Conflicting object already exists (violated constraint 'uc_org_name'): Conflicting object already exists (violated constraint 'uc_org_name')

The problem in field 'name_norm' in database. It's empty when Name in russain, so new org unit tries to make one more empty name_norm. And beause it CONSTRAINT in database, there is an error.

Another problem from here - it's not possible to create org unit with same name in different Orgs. I think it's better to make constraint field like Indintifier, not name.
