Furthermore--you probably know this because of the conversation 
on GitHub but for anyone else reading--narrow strings are also 
hard to work with because you can't put a dchar on them 
currently. Kenji had a pull request (since closed) to help with 
narrow strings issues:

That and all the issues and unknowns you describe would need to 
fixed for output ranges are going to be the approach.

I'm reminded of a forum post by monarch_dodra that talked about 
some of the issues you brought up:
