The problem is that GHC's output functions only print the lowest 8
bits of each code point. To print these higher code points, you'll
need to translate your [Char] into a byte encoding that your terminal
will understand (most likely UTF-8). I know there are several of
these floating around in the wild, hopefully someone will chime in
with a code snippet soon. Also, I seem to remember that Bulat's
Streams library supports some Unicode encodings, perhaps you can
