1. You need to use "chcp 65001" to set the console code page to UTF8

foo.txt. If you open this file in notepad you will see the correct
characters show up.
it will work even without chcp. afaik nor ghc nor windows adjusts text
being output to current console codepage
GHC certainly does. We use GetConsoleCP() when deciding what code page to use by default - see libraries/base/GHC/IO/Encoding/CodePage.hs.
This can actually be quite helpful. I've discovered that if you have a console set to code page 65001 (UTF-8) and use WriteConsoleA (the non-wide version) with UTF-8 encoded strings, the console displays the text properly!
So the solution seems to be, when outputting to a utf8 console use WriteConsoleA.
