spam in foreign characters

[Adam Moffett]

I have a user who seems to get 4-5 messages per day with Chinese 
characters for the subject and body.  They come from a variety of 
domains and IP's so I guess she somehow got onto a list used to spam 
Chinese speaking people.

If I paste them into Google Translate they seem to be roughly the same 
kind of junk as our English spam: "work from home", "buy our drugs", 
etc.  The handful that I looked at closely had scores of 2.0-3.0.

Are there existing SpamAssassin rules that work on non english 
characters?  Is there maybe something extra I should enable or install 
that would score these higher?

I'm sorry if it's an ignorant question, but the issue hasn't really come 
up here before.

Thanks.
