That sounds correct. The cx_Oracle.UNICODE type constant is present when
cx_Oracle is compiled *without* the WITH_UNICODE option (which no longer
exists in 5.1 anyway).

Strange, in 5.1 it shouldn't make any difference which is used, as long as
your NLS_LANG is getting set properly in the backend. What is your server
setup? It seems that sometimes that can get interfered with if you have
other services using Oracle in the same process. It shouldn't hurt
anything though for us to do an additional check for cx_Oracle 5.1+ and
always use force_text in that case.
