Yeah, that's not the same thing as an actual Unicode string, and 
requires handling of all sorts of "what if someone sticks non-Unicode in 
there?" issues...

Of course people actually do use JS strings as immutable arrays of 
16-bit unsigned integers right now (not just as byte arrays), so I 
suspect that we can't easily exclude the surrogate ranges from "strings" 
without breaking existing content...
