Add new contact in Webex teams app if the email address includes German character in it (such as ä)

When the customer tries to add a custom contact with special German characters, he gets an error message:

error : Email you entered is not valid/ Failed to save the contact - attached

Workaround is not to use "ae" or "oe" because another user will not receive an invitation to a meeting, for example.

The problem was fixed by the customer after reviewing this email on this page https://www.domaintechnik.at/idn-converter.html.

The customer want to have possibility to add new custom contact if the email includes German character(such as ä).
