Subject: [PATCH] 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!
