You can reopen sys.stdout with a different encoding and replace sys.stdout. I don't remember the exact recipe, it's tricky if you want portable code (you have to take care of newline).

For example, I wrote:
http://hg.python.org/cpython/file/ebe28dba4a78/Lib/test/regrtest.py#l895

But you can avoid reopening the file using stdout.detach().

Many options were already proposed. Another way, less convinient is to use sys.stdout.buffer.write("text".encode(encoding)) (you have to flush sys.stdout before, and flush the buffer after, to avoid inconsistencies between the TextIOWrapper and the BufferedWriter).
