Backwards compatibility is important, but not an absolute. I’d be curious if anyone can point to instances where software might _rely_ on the show instance for strings not displaying unicode characters?
This will break a bunch of my doctests, but I can just update them. I would be more concerned about what happens in a terminal/font that doesn't have unicode support. For the font at least, my xfce4-terminal does something intelligent and falls back to another font that does have the fortune cookie symbols. But for the terminal? Try Ctrl-Alt-F1 to drop out of X and into a Linux/BSD terminal, and runghc on a file containing, main = mapM_ putStrLn $ [(++"の父"), (++"の母")] <*> ["田中", "山田"] I get a bunch of grey question marks.
