I think this was a misunderstanding during the issue 3745 processing: the patch should not have been backported to trunk at all. For Python 3.x, the change was correct. For 2.x, a -3 warning would have been a better fit. Note that the non-OpenSSL SHA et al. modules have never defaulted to encoding to UTF-8 in Python 2.x. Python 2.x uses ASCII as default encoding. Only Python 3.x uses UTF-8 as default encoding. I've added a note to the issue and reopened it. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Dec 15 2009) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try our new mxODBC.Connect Python Database Interface for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
