[Exim] Problem with special characters in Spam mail.

Hi.

The Spam I am receiving is not being catched by SpamAssassin and the
filter for it makes everything work wrong. That is, I just stop recieving any
mail at all.

The problem is because the subject line o this spam has special characters.
In my .forward file I've got:

if $message_headers: contains "X-UKC-CSSpamCheck-Flag: YES" or
   $h_subject: contains "Have ä grëat night toníght"
then
        save "$home/Mail/spam" 0644
        seen finish
endif

Because of the special accents on this subject line everything stops working.

Is there any way to set-up this filter through the subject line? Any other suggestions?
I am also trying to filter the sender/reciever, but it is not working because it varies too much.

PS: Please carbon copy any reply answer to my e-mail (I am not subscribed in the mailing list)

regards
leo
