Configuring a domain alias containing an umlaut

Hello! I am trying to add a domain alias that contains an Umlaut character (“ü”). The form in project > settings > domain management blocks input of this character. Is there another way to add my domain alias?

I searched the forums and Google and did not find an answer to this question.

Thank you!
