This seems worthwhile in its own right, but also works around an Oracle bug (in versions 10 -- 11.1) where the use of Unicode would reset the date/time formats, causing ORA-01843 errors. Thanks Trac users CarstenF for the report, jtiai for the initial patch, and everyone who contributed to the discussion on the ticket. Backport of 6983201 from master.
