spamassassin is pretty good at catching "faraway" charsets if you set
the score high enough on those tests. (the debian package sets them
to 0 by default so as not to discriminate against foreign users)

I added a couple of tests myself for things that slipped just under SA
(I set the CHARSET_FARAWAY test to a score of 4, 5 is the threshhold;
a few messages that aren't spam have triggered that test) :

~~~~~~~~~~~~
header      BAD_CHARSET1    Subject =~ /=\?UNKNOWN\?/
header      BAD_CHARSET2    From =~ /=\?UNKNOWN\?/
header      BAD_CHARSET3    Subject =~ /=\?ks_c_5601-1987\?/


score       BAD_CHARSET1    5
score       BAD_CHARSET2    5
score       BAD_CHARSET3    5



header  KOREAN_SPAM     Content-Type =~ /charset=ks_c_5601-1987/
score   KOREAN_SPAM     5
~~~~~~~~~~~~
