Win py27 issue (#13595)

* change to the processor to check for BOM at the beginning

* changes to serialize and deserialize to be consistent with py2/3 strings/unicode types. new recordings for all that, changes to tests for everything, and a bug in sas file

* forgot to add a unicode explicitly, re-recorded some tests because of that
