You cannot replace the above filters with one that does the same thing
(This needs regular expressions, which the IMAP4rev1 doesn't support).

Some IMAP mail servers accept something like:

  mask header Content-Type "text/html; charset=\"euc-kr\""

This probably accomplishes what you want:

filter spam and
  mask header Content-Type text/html;
  mask header Content-Type euc-kr
  or header Content-Type gb2312
  or header Content-Type ks_c_5601-1987
  or ...
action delete
