A Unicode string as an abstract data type has no encoding. It is a 
Platonic ideal, a pure form like the real numbers. There are no bytes, no 
bits, just code points. That is what Ethan means. A Unicode string like 
this:

s = u"NOBODY expects the Spanish Inquisition!"

should not be thought of as a bunch of bytes in some encoding, but as an 
array of code points. Eventually the abstraction will leak, all 
abstractions do, but not for a very long time.
