A system not supporting non-latin characters in personal names is pitiful, but a system telling the user that they have an invalid name is outright insulting.

That’s the best one of the lot. "Dein Name ist ungültig", "Your name is invalid", written with the informal word for "your".

They're trying to say that you and the server are very close friends, you see? No, no, I get this is not correct, just a joke...

It's only insulting if you want to be insulted. You'd do better learning to understand that its a computer system and not a personal attack.

While I agree with you that an error message like this should not be taken as a personal attack, it still causes a horrible user experience. It’s not like the developers of these systems had no choice in the wording of these errors: they picked the insensitive computer-says-no option, while they could have went with an apologetic “Sorry, our system does not support special characters” instead.
