Comment (by RyanGlScott):

 OK, thank you for confirming. As I
 [https://ghc.haskell.org/trac/ghc/ticket/7593#comment:6 noted] in #7593,
 just changing the encoding to `utf8` is a sufficient fix for `mintty`, but
 it's not enough for `cmd.exe`. For the latter, the only solution I've
 found was to use native Windows console API functions such as
 `WriteConsoleW` and `ReadConsoleW`. This only works for `stdin`/`stdout`,
 though, and not general file IO.

 I imagine it would be a pretty significant time investment redesigning
 Haskell IO to use Windows API calls everywhere, though.
