 Last night I updated my PC to the 14965 Windows insider build. Today I
 notice that `getLine` no longer terminates (pressing enter just goes to a
 new line), but I'm suspecting that the root cause it that `getChar`
 returns `'\NUL'` no mather what is input.

 I've tried this both GHCi and in a compiled program.

 This is only broken if I set my codepage to 65001 (UTF-8). If I set it to
 something like 850 it works as it should.
