[Exim] Spam trick?

Hello list,

This spam ended up in my mailbox. Notice the spaces in the spelling of
the product advertised. A trick to fool spam filtering software? If yes,
can it be caught?

       For the first time ever, a generic version of V i a g r aÿFFFFAE
       is available to you.
       GSC-100, the generic equivalent of V i a g r a, gives you the

       exact performance and power as V i a g r a, for HALF THE COST.
                                      ^^^^^^^^^^^
