Perhaps more useful - and less prone to FPs in internationally-oriented 
organisations - a rule that spots *mismatched* charsets, e.g. a Cyrillic 
charset from a Chinese IP, a Korean charset via an Italian freemail 
host, and so on.

I guess such a rule would be possible as a meta, though an eval function 
might be more effective and allow more combinations.
