I didn't write anything about "not an abstraction" -- do you mean 
"non-leaky abstraction"? Those are rare birds.

Iterators forward and (if needed backward) over Unicode characters 
(scalar values; I'm allowed to call those "characters", no?) would be 
good. Github beats TC39 as usual, prollyfill FTW.
