Stopping unwanted character sets

There was some discussion a while ago about stopping messages based on
country of orrigin.
But I see more use in stopping unwanted charactersets.
I have no need for messages in this character set nor anyone else.
Is there a way to filter on these?
I can find them if they mess with the subject line in postfix with:
/^Subject: =\?KOI8-R\?/ REJECT Russian encoding not allowed here.
/^Subject: .* =\?windows-1251\?/ REJECT Crappy propriatary encoding not allowed here.
/^Subject: .*\[windows-1251\]/ REJECT Crappy propriatary encoding not allowed here.
/^Subject: =\?windows-1252\?/ REJECT Crappy propriatary encoding not allowed here.
But what if it is proper MIME message and the character set is used only
in some mime parts?
Is there a SA ruleset for this? (Or even a postfix trick to do this.)

Some men see computers as they are and say "Windows"
I use computers with Linux and say "Why Windows?"
(Thanks JFK, for the insight.)
