Fair question...
I've got a dozen or more email addresses that funnel into my mailbox.
Consequently, I get a tremendous amount of spam.
My filter first sorts mailing list email into separate mailboxes.
Then it agressively looks for anything resembling spam and throws that
into a spam mailbox which I periodically review. The test above looks
for 5 non-ASCII characters in a row which catches a lot of Asian spam,
such as:
Subject: <<B1><A4><B0><ED>> <C8><AB><BA><B8><B0><A1>
<C7><CA><BF><E4><C7><CF><BD><C3><C1><D2>?! <C0><CC><C1><A6>
<C0><CC><B8><DE><C0><CF><B8><B6><C4><C9><C6><C3><C0><B8><B7><CE>
<BD><C3><C0><DB><C7><CF><BD><CA><BD><C3><BF><E4>!!!
(I hope that subject line wasn't too racy.)

Without 5 consecutive non-ASCII characters, it would not be caught by
my test.
