For best backward compatibility, I would say Copy, Length, Pos etc should work by "character based" by default. Then introduce more optimised versions like ElementCopy, ElementLength, etc... Old programs will work out of the box, but might experience a minor speed penalty, until the developer has time to convert to the more optimise calls. Just a thought? And to replace SomeString[x] code with a unicode safe / equivalent, we can implement a CharAt(str, x) method.
