Mark Dickinson dicki...@gmail.com added the comment: One *could* add a check in pythonrun.c to substitute some suitable default (UTF-8) if nl_langinfo(CODESET) returns an empty value. While googling for the source of this problem, I found other software projects that take this approach. It

Ronald Oussoren ronaldousso...@mac.com added the comment: The manpage says that nl_langinfo returns an empty string when there is an invalid setting. There is validity in saying that 'LANG=utf-8' is an invalid setting, the LANG variable is supposed to a locale name, which would be a language

Mark Dickinson dicki...@gmail.com added the comment: There is validity in saying that 'LANG=utf-8' is an invalid setting Agreed. But that doesn't really explain why e.g. LANG=en_US also produces , while LANG=invalid produces US-ASCII. I do wonder how the user ended up with LANG=utf-8 in

Ronald Oussoren ronaldousso...@mac.com added the comment: The attached patch (issue6393-fix.patch) seems to fix the issue. Could you please test and have a look at the patch? It basicly tests if the output of nl_langinfo(CODESET) is the empty string and defaults to 'UTF-8' in that case (but

Mark Dickinson dicki...@gmail.com added the comment: Thanks, Ronald! The patch fixes the problem for me. (I directly patched the locale.py file installed from the Python dmg, since I still haven't figured out how to build a python executable that exhibits this problem.) The patch doesn't look

Ned Deily n...@acm.org added the comment: This is a side effect of the fix for Issue6202. Prior to r73268, locale.getpreferredencoding always returned mac-roman regardless of the setting of LANG, so this wasn't a problem in py3k (or 3.0.x builds) up through 3.1rc1. I can reproduce it on

Ned Deily n...@acm.org added the comment: Note, you can produce the same error on OS X or linux by setting PYTHONIOENCODING=, which effectively overrides the value returned nl_langinfo(CODESET). In pythonrun.c, create_stdio passes PYTHONENCODING, if set, on as the encoding value to
