The only solution is defensive programming. Even if there were a standard
that everyone followed, if malicious people could break things by not
following the standard, then you can be certain that somebody would do so.

Thank you very much. However, I think even this is too optimistic:

Shouldn't it be something like:
if ((*s & 0x80) && (*(s+1) & 0x80))
Even though "\242\242\242\0" is an invalid EUC sequence, it still shouldn't be
allowed to break the software.
