The zpublisher-encoding usually must not have something to do with the
encoding of ZPTs. The manage_page_charset would make sense since it can be
specific to a particular subfolder. However we can't use acquisition with
the phase where the migration happens (__setstate__()).

Zope will raise an exception if it can't autodetect the encoding. However
the current implementation does not store the changes back. So the original
data in the ZODB remains untouched until the user clicks on 'Save'.
