Punycode support

[zoolander]

Hello!
It might be a niche thing, but maybe you could add support for punycode domains, when connecting to a server directly. I own a domain with a german umlaut and it is not possible to join my factorio server with that address. Instead one receives the message "... is not a valid address (No such host is known. )."
It is still possible to connect, but you need to know the actual address, that the domain would resolve into.
For example: The actual address of ö-is-a-german-umlaut.de would be xn---is-a-german-umlaut-p6b.de, but as you can imagine the latter is kinda hard to remeber. Punycode support would make sharing the server with other people somewhat easier in my opinion.
Thanks and have a merry christmas!
