The pull request contains some more arguments against option 2:

* different type for "ref" compared to non ref is unprecedented
* won't fix iteration for composed characters
* what if iteration over code point was intended in the first place? Silent
breaking change

I'm personally particularly interested to fix the foreach over a unicode
literal. I guess we could change the type of such a literal and, for example,
pick a type that fits the characters in the literal.
