[cx-oracle-users] Client encoding under Cygwin

[Ian K. <ian...@gm...>]

Using:
Cygwin 2.721 under Windows XP SP3
Python 2.5.5
cx_Oracle 5.0.3
Oracle 10.2.0

I can't seem to change the client encoding used by cx_Oracle.  I've tried this:

$ export NLS_LANG=.UTF8
$ python
Python 2.5.5 (r255:77872, Mar 15 2010, 00:43:13)
[GCC 4.3.4 20090804 (release) 1] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ['NLS_LANG']
'.UTF8'
>>> import cx_Oracle
>>> conn = cx_Oracle.connect('ikelly/ikelly@xe')
>>> conn.encoding, conn.nencoding
('WINDOWS-1252', 'WINDOWS-1252')

I've also tried fiddling with the NLS_LANG registry setting, also to
no effect.  Any ideas?

Thanks,
Ian
