The console behaves by encoding a str (using the sys.getdefaultencoding()) and then decodes the bytes to a glyph for rendering. The decoder used is 'cp437'. Apparently, there is no way to override that!
See ipython notebook for summary and example of the issue.

Hi, when you say "The console" is the the old MS-DOS command ("Windows console") opened when you run the "cmd.exe" program? Or IDLE or another console?
For the Windows console, see the old issue bpo-1602 which is not fixed yet.
On Windows, sys.stdout.encoding is your OEM code page, which is usually different than the ANSI code page (locale.getpreferredencoding()).

You can change the code page of a Command Prompt window, before calling Python, with ...> chcp <code-page>. There is 'something' called cp65001 that is supposed to be a utf-8 codepage. Once can change to it, but it does not work right. This has been discussed on StackOverflow and elsewhere.

I start ipython in Windows PowerShell. The "console" I am referring to is
ipython running in WindowsPowerShell.
I do not use the DOS cmd.exe
When running ipython notebook from WindowsPowerShell -- no problem printing
unicode.
When running in PTVS (Python Tools for Visual Studio) debugger -- no
problem printing unicode in Output window, or Interactive Python window.
Problem does appear in Console window (which is the DOS window I believe).
