In Jython we have such an encoding that can be set with the -E codec flag or a registry option (the moral equivalent of env var for CPython settings), at the moment AFAIK it is is only used for the interactive prompt input, whereas you presumably intented a default encoding for sys.stdin/out.

Indeed. I would check whether sys.stdout isatty() before applying the encoding. In the Windows (NT) console window, MS has special API to output Unicode, on other systems, the console encoding would be used.

For sys.stdin, it would never be used, but just exposed to the application for converting input if it wants Unicode. The only exception might be raw_input(): In IDLE, raw_input() will natively return Unicode strings; I'm not sure whether IDLE should attempt to convert them to byte strings, or whether it should return Unicode strings from raw_input().
