Where in the strawman is anything of that kind observably (to JS authors) proposed?

Yes, old APIs for building strings, e.g. String.fromCharCode, still build "gunk strings", aka uint16 data hacked into strings. New APIs for characters. This has to apply to internal JS engine / DOM implemnetation APIs as needed, too.

Seriously, I think we should try to make a list of the issues there, the pitfalls that would arise for web developers as a result, then go through and see how and whether to address them. Then we'll have a good basis for considering the web compat impact....
