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.

For 3.x, I'd like to see a PYTHONSTDINENCODING, because the current
way of relying on the terminal encoding does work well... it then
falls back to ASCII, which prevents entering e.g. German Umlauts.
