That should be okay, we would just configure Python or Django to use a different default encoding. But the trouble is, we can't. In tzinfo.py the default encoding is determined as locale.getdefaultlocale()[1], which calls _locale._getdefaultlocale(), which on a Mac calls CFStringGetSystemEncoding. Of this latter function, the Mac documentation says: ''In Mac OS X, this encoding is determined by the user's preferred language setting. The preferred language is the first language listed in the International pane of the System Preferences.'' So there appears to be no way, in some locales, to get Django to render pages. One is forced to change the user's global language preference in the operating system settings. That's a bit too inflexible. In contrast, sys.getdefaultencoding is easily controlled by calling sys.setdefaultencoding in sitecustomize.py. Thus tzinfo.py should obtain the default encoding using sys.getdefaultencoding instead — at least optionally, or perhaps as a special-case exception for the mac-specific encodings, if one wants to take great care to minimize behavior changes in working installations.",,closed,Core (Other),1.0,,fixed,locale encoding getdefaultlocale getdefaultencoding mac,,Ready for checkin,1,0,0,0,0,0
