Describe the bug

Creating a user with japanese signs in the local part of an email address fails without an error message, in the admin UI.

• Create a realm with email as username setting
• Go to Admin UI and create a user with this email address: あいうえお@example.com
• Click "Create" -> nothing happend in the frontend

In the backend, there was a 400 error thrown.

This kind of email address is technically not a valid email address. The UI validation and the api validation should reject this kind of email address. But not the email validator is the source of the error, instead the username validator throws the error.

When you try to create a user with this email address via Admin API, you will get this error:

Error creating user: error-username-invalid-character
