Forwarding to the tutor list with cut n paste sessions. It looks to me like the code page issue somebody else referred to is the problem but the behaviour seems a bit extreme, I'd have thought it might have chosen a default value or something...
But I'm not sure what causes it to select cp720 in the first place. Where does Py_Initialize get its values? Are they set in the environment somewhere? And why is 2.6 OK? I know 3.0 did some changes around locale handling but I can't recall what they were. I assume this is a side effect of those changes?
