And does this work for Non-GHC yet? And when does it get added to

Yes, this a decent layering of (2), on top of (1), for GHC only,
depending on it to reading the bytes, and interpreting them as Latin-1.

It's not obvious that ByteString is the place to look for I/O, so it's
not yet good enough. It should be as easy to use as character I/O, and as
easy to find.
