Hmmm, "String -> [Word8]" would be nicer...

... and here: "[Word8] -> String" or "[Word8] -> Maybe String".
Furthermore, UTF-8 is not restricted to a maximum of 3 bytes per character,
here an excerpt from "man utf8" on my SuSE Linux:
* UTF-8 encoded UCS characters may be up to six bytes
long, however the Unicode standard specifies no characters
above 0x10ffff, so Unicode characters can only be up to
four bytes long in UTF-8.
IIRC we discussed encoders/decoders quite some time ago on the libraries
mailing list, but nothing really happened, which is a pity. We should
strive for something more general than UTF-8 <-> UCS/Unicode, there are
quite a few more widely used encodings, e.g. GSM 03.38, etc. Any takers?
