wren is half right:  at the level of Unixy APIs (and this includes anything
that goes on in a Terminal window and anything that you will be doing from
Haskell) you use UTF8, but OSX APIs --- that is, Carbon and Cocoa --- use
UTF16.  So for the purposes of ghc/jhc OSX is UTF8, but if someone wrote a
"fully native" Cocoa-based runtime it would use UTF16.  (Compare Win32 APIs
to mingw APIs; very similar situation.)
