How to filter based on "garbage" subjects ... ?

[Marc G. Fournier]

I've yet to be able to come up with a sieve rule that will allow me to
filter all "garbage" subjects to a seperate folder ... you know the ones
that look like:

Subject: =?euc-kr?q?(=B1=A4=B0=ED)=B5=F0=C1=F6=

I've even tried to use Pine filtering to filter based on 8bit subjects,
but it doesn't pick them up either ...

For instance, under Pine, if I try to select all subjects with =B1= in
them, which the above contains, it selects nothing, so I'm figuring there
has to be some control characters in there somewhere ... ?

Thoughts?
