Sounds like you want to say that string should be smarter than an 
array of code units in dealing with unicode. As I understand, 
design rationale behind strings being plain arrays of code units 
is that it's impractical for the string to smarter than array of 
code units - it just won't cut it, while plain array provides 
simple and easy to understand implementation of string.
