Reference (unpatched): haypo@selma$ env -i LC_ALL=C ./python -c "import locale; print(locale.getpreferredencoding())" Python runtime initialized with LC_CTYPE=C (a locale with default ASCII encoding), which may cause Unicode compatibility problems. Using C.UTF-8, C.utf8, or UTF-8 (if available) as alternative Unicode-compatible locales is recommended. ANSI_X3.4-1968 haypo@selma$ env -i LC_CTYPE=C ./python -c "import locale; print(locale.getpreferredencoding())" Python detected LC_CTYPE=C: LC_CTYPE coerced to C.UTF-8 (set another locale or PYTHONCOERCECLOCALE=0 to disable this locale coercion behavior). UTF-8 haypo@selma$ env -i LC_ALL=C ./python -c "import locale; print(locale.getpreferredencoding())" Python runtime initialized with LC_CTYPE=C (a locale with default ASCII encoding), which may cause Unicode compatibility problems. Using C.UTF-8, C.utf8, or UTF-8 (if available) as alternative Unicode-compatible locales is recommended. ANSI_X3.4-1968 With my change: haypo@selma$ env -i ./python -c "import locale; print(locale.getpreferredencoding())" UTF-8 haypo@selma$ env -i LC_CTYPE=C ./python -c "import locale; print(locale.getpreferredencoding())" UTF-8 haypo@selma$ env -i LC_ALL=C ./python -c "import locale; print(locale.getpreferredencoding())" ANSI_X3.4-1968 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30565> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
