Spam filters for emails in outlook 2007?

Hi,

does anyone know whether I can define eMail filters in outlook 2007 in order to direct spam mails into other folder?

Up to now I use the firefox  for my yahoo mails but I realized that some spamers use utf-8 encodings

in the subject and in the mail body, so my defined filters apply probably before decoding to ASCII.

I think it's because of this.

But filters with "contain" "utf-8" didn't apply too...I hope therefore outlook 2007 could be a solution....

Thanks
