Quick and dirty ZNC filter to stop people from crashing clients (no longer needed as of 10.8.5)

filter.cpp

#include <znc/Modules.h>

using namespace std;

static const char evil[] = { (char)0xd8, (char)0xb3, 0 };

class CFilterMod : public CModule {
public:
	MODCONSTRUCTOR(CFilterMod) {
	}

	virtual EModRet OnChanMsg(CNick& Nick, CChan& Channel, CString& sMessage) {
		if (sMessage.find(evil) != string::npos) {
			return HALT;
		}

		return CONTINUE;
	}
};

MODULEDEFS(CFilterMod, "Message filter module")

1. znc-buildmod filter.cpp
2. Copy filter.so into ZNC modules directory
3. /msg *status loadmod filter
