Re: [web-annotation] (model) vague definition of charactor position for text position selector

I'd like to bring to this issues attention a [recent query against the
 EPUBCFI 
specification](https://github.com/IDPF/epub-revision/issues/555), 
which may be used as fragment identifiers within this spec, where it 
was (tentatively?) decided that character positions be defined in 
terms of UTF-16 code units.
It might be confusing if this spec chooses unicode code points but the
 EPUBCFI spec chooses UTF-16 code units...

Is this specification in danger of being too difficult to implement 
atop the current state of deployed ECMAScript and browser DOM APIs 
(where UTF-16 code units are the lingua franca)?

Are changes to browser DOM APIs (for example allowing unicode code 
point indexing within DOM Ranges and others) imminent?
