New submission from Markus Kettunen: In a C application on Windows, at least on MSVC 2010 and Windows 7, do this:
wprintf(L"Test\n"); Py_Initialize(); wprintf(L"Test\n"); Output is: Test T e s t I was able to track the issue to fileio.c to the following code block by searching where wprintf breaks: if (dircheck(self, nameobj) < 0) goto error; #if defined(MS_WINDOWS) || defined(__CYGWIN__) /* don't translate newlines (\r\n <=> \n) */ _setmode(self->fd, O_BINARY); <----- breaks it #endif if (PyObject_SetAttrString((PyObject *)self, "name", nameobj) < 0) goto error; This can be easily confirmed by adding wprintfs on both sides of _setmode. This issue was also raised at http://mail.python.org/pipermail/python-list/2012-February/620528.html but no solution was provided back then. ---------- components: IO, Unicode, Windows messages: 176732 nosy: ezio.melotti, makegho priority: normal severity: normal status: open title: Py_Initialize breaks wprintf on Windows type: behavior versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16587> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
