New issue 3507: revisit cx_oracle unicode handling
https://bitbucket.org/zzzeek/sqlalchemy/issues/3507/revisit-cx_oracle-unicode-handling

Mike Bayer:

cx_oracle types that subclass _NativeUnicodeMixin but not _OracleUnicodeText are essentially text types where convert_unicode=True/'force' is entirely non functional.  Even if the cx_oracle coerce_to_unicode flag is turned on, which we no longer recommend, a CLOB will never return unicode.  this needs to be worked out so that the public flags at least do as expected.
