I don't have access to OSX to try out things,
but I suspect ko_KR.UTF-8 may not be supported on your system?
Can you try instead with LC_ALL=en_US.UTF-8 or LC_ALL=C,
both of which display correctly on Fedora Linux here.

Also what's the output from:

  LC_ALL=ko_KR.UTF-8 locale

If that suggests ko_KR.UTF-8 is supported,
then I'll need to get access to an OSX system to debug.
Perhaps there is some shennanigans with the returned charset on OSX.
