Although I am not sure exactly what types of pencil marks are
referred to, I have never had a problem encapsulating documents
which include normal writing and marks with a #2 or similar pencil.
Were this to be charcoal writings, etc., then that would be a
different situation.  I would test the stability of the pencil by
encapsulating similar documents and seeing whether or not the pencil
lifts off.  I would doubt it, if it is our normal graphite pencils.
