I'd like to propose a new environment variable PYTHONSTDOUTENCODING. This is meant to solve various problems that people had with Python not detecting their terminal encoding correctly; it would override any detection that Python would use for determining the encoding of stdout (and stdin - but that's less relevant in 2.x).

How is this relevant for 2.x ? In 2.x, stdin and stdout are just files without any io wrappers around them. Writing Unicode to stdout will still use the default encoding ASCII to convert it to an 8-bit string. All other 8-bit strings will be passed to stdout as-is.

You're forgetting about print; in Python 2.x, when stdout is connected to a terminal, the locale settings (typically the LANG, LC_ALL and LC_CTYPE environment variables) are taken into account when 'print' writes to sys.stdout.
