On Windows, you can use WriteConsoleW() with
GetStdHandle(STD_OUTPUT_HANDLE).  I have no clue how this will behave
if your stdlib buffers output.  In VC++ specifically (2005 and up) you
can do _setmode(_fileno(stdout), _O_U16TEXT), and wprintf() and wcout
will behave properly for all Unicode text.

You still need to set the console's font to one supporting Unicode
glyphs, though.
