eryksun added the comment: The problem is skip_whitespace mistakenly calls isspace instead of iswspace.
http://hg.python.org/cpython/file/c0e311e010fc/PC/launcher.c#l48 isspace has undefined behavior when the argument is "not EOF or in the range of 0 through 0xFF": http://msdn.microsoft.com/en-us/library/y13z34da%28v=vs.100%29.aspx The display of debug messages should be handled in its own issue. IMO, setting stderr to _O_WTEXT mode or _O_U16TEXT mode looks reasonable. The launcher already uses wide-character strings and the wprintf family. It's just the default _O_TEXT mode ends up encoding to the console codepage. Regarding msg206744, %s in wide-character format strings is OK for VC++ 10: http://msdn.microsoft.com/en-us/library/hf4y5e3w%28v=vs.100%29.aspx This will be a legacy mode in VC++ 14 (CPython 3.5?): http://blogs.msdn.com/b/vcblog/archive/2014/06/18/crt-features-fixes-and-breaking-changes-in-visual-studio-14-ctp1.aspx P.S. In case someone wants an easy issue, I noticed a bug. There should only be one %s in the format string that starts on line 262: http://hg.python.org/cpython/file/c0e311e010fc/PC/launcher.c#l262 ---------- nosy: +eryksun _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20042> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
