[Bug] Server Crash (pyspades)

[Jouh]

Hey guys,

since a week I'm hosting a small Pyspades server on a linux machine (Vserver). Im amazed how smoothly it ran until now, but yesterday I had the second crash in two days. So I have two questions, but beforehand I'll show you the tracesback:

   exceptions.UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2: ordinal not in range(128)

Is it possible for some capable person to send malformed packets that can lead to a crash? It doesn't necessarily be the cause of _this_ problem here, but I'd be interested if ppl know something about it and if yes so, if there is some sort of enhancement coming.

Second thing is: What exactly led to the server crash here? From what i read out of that traceback, there's some ASCII symbol that cant be encoded connected to the rampage script- is that the common Ä/Ö/Ü/ß problem pyspades got? Or is it something special here? Maybe there is someone with special characters in name going on rampage? I dunno...

Thanks for your help in advance,

Jouh

I've seen that sort of thing.. it'll show up that there was an error from an IP & then it shows a bunch of slashes like /%\Ø/¶ but longer... at one point my system restarted... I don't see the need for these extra characters in the game personally... I think I may have saved one of the errors... if I find it I'll post it

it's gone.. but next time I see it I'll save it..

Well, since I'm hosting a server that shall be (at the moment) mainly for german ppl, special chars are needed - as are for austrians or swiss.

My question is: Is this assumption correct? Do those characters really cause the servercrash?
