The OP_RealAffinity opcode is not necessary after reading values from a virtual table (such as rtree). It is harmless, but it does use CPU cycles. Might as well leave it off. (check-in: dc18d89354 user: drh tags: trunk)

Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence.
