Log:
Fix Unicode output on the console, broken in 33866, fixed in 34042, broken again in 38185,
fixed again in 51058 and finally broken yet another time since 54651...
I think this history deserves champagne and forceful warning comments, which have been
added.
Simple solution: Don't blindly sync Wine code!
