Yes, on Linux, it "just works": haypo@selma$ LC_ALL=en_US python2 -c 'import io; io.open("/dev/null")' haypo@selma$ LC_ALL=en_USxxx python2 -c 'import io; io.open("/dev/null")' In fact, you get ASCII encoding for these two locales: haypo@selma$ LC_ALL=en_US python2 -c 'import locale; print(locale.getpreferredencoding(False))' ANSI_X3.4-1968 haypo@selma$ LC_ALL=en_USxxx python2 -c 'import locale; print(locale.getpreferredencoding(False))' ANSI_X3.4-1968 Internally, io.open() uses locale.getpreferredencoding(False) if you don't specify an encoding. ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30338> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
