In Unicode 4.0.1, Chapter 3.9:

 D30a Well-formed: A Unicode code unit sequence that purports to be in a
      Unicode encoding form is called well-formed if and only if it does
      follow the specification of that Unicode encoding form.

    - A Unicode code unit sequence that consists entirely of a sequence
      of well-formed Unic ode code unit sequences (all of the same
      Unicode encoding form) is itself a well-formed Unicode code unit

Thus, since any code unit sequence representing a single Unicode scalar
value is itself well-formed, any sequence of encoded code points is
