If you can iterate linearly, Unicode is indexable...

Sorry, you don't get it. I'm using a very specific meaning of indexable, probably that is the problem.

A vector is indexable. You can reach v[7] without going though 0 to 6 and 0 though 6 can't do anything to change the "offset" of 7. A list is not. You need to traverse it to get list[7].

That sound to me like you trying to make String indexable. Which can't be done with Unicode. How are you going to determine the sequence of bytes that you must return for a position without traversing it linearly?

Not so sure about this - not that important IMO at this point. So I will not get correct ToUpper for many characters - that has little impact on most applications.
