You are being ironic, I take it?
Unicode by its nature implies multi-byte chars, it's just a question
of how they are encoded: UTF-8 (one or more bytes, variable), UTF-16
(two or four, variable), or UCS-4 (or should it be UTF-32? - four
bytes, fixed). The problem here is that while terminal software have
been UTF-8 for some time, GHC only recently caught up.
If I haven't seen further, it is by standing in the footprints of giants
