Mail filter

[RA]

Is it possible to design a filter that can reside in my mailbox in the mail server that can delete any mail that comes with the subject containing any of these special characters?  ([����]�������� ũ���������� ���� Ư���� ȣ��) Most of them are coming from Korea, Taiwan and China and a few from Russia. I am not expecting any mail that is not in English or a European language. Please let me know if possible. Any help is greatly appreciated. Thanks.
