Server crashes when someone with an abstract name connects

As in the title, my server crashes whenever someone with a downright SHITTON of symbols in their name connects.

Is there any way to fix/stop this crap from happening? (It’s happening to a few other people i’ve asked too, so it’s not just limited to me.)

Only when connecting, or downright when they appear in the server?
You could probably try with an autokick of sorts or IPban until they remove the characters, i dunno.

If it’s on player spawn I’d use Gatekeeper to auto kick anyone without any ascii characters in their name.

Yeah, fuck them. If your going to join, make your name decent, other then a mass of symbols to make us hate you more.
