[Haskell-beginners] Simple UTF-8 output

[Elvio Toccalino]

I usually pull such values as ByteStrings. The utf8-strings package
provides printing functions for such data.
Also, if you'd like to work on it as Text, there's the
Data.Text.Encodings module, to decodeUTF8 or decodeASCII ByteString's
into Text.
