Use both?

I am not familiar with Text, but UTF-8 is pretty awkward, and I will
sure look into Text before wasting any time trying to fine-tune my
ByteString handling for UTF-8.

But in practice only a fraction of my data input will be manipulated
in an encoding-sensitive context.  I'm thinking _all_ data is binary,
and accordingly all inputs are ByteString;  conversion to Text will
happen as needed for ... uh, wait, is there a conversion from
ByteString to Text?  Well, if not, no doubt that's coming.
