That depends on what you mean by "base on vector". To me, basing Unicode strings 
on vectors means that vectors are an implementation detail and that the client 
of the Unicode string abstraction is not allowed to make arbitrary changes to 
the vector. (In other words, the Unicode string abstraction maintains all the 
invariants pertaining to Unicode.)
