[Haskell-cafe] Unicode strings

[Spencer Janssen]

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  
check there?


Cheers,
