And a sequence of bytes is exactly the same thing as a UTF-32 string,
when the sequence is encoded as UTF-32.

But that is not the point. The point is that when some function is
handed a ByteString, the ByteString can be encoded in many ways. It do
not even have to be text.

So you need a UTF-8 String type.
