Jython uses UTF-16 internally -- probably the only sensible choice in a

Indexing can be made O(log(k)) where k is the number of astral chars,
and is usually small.
I like your idea and think it would be great if Jython will implement
it.
A proof of concept implementation in Python that handles both indexing
and slicing is on the tracker. It is simpler than I initially expected.

I mentioned it as an alternative during the '393 discussion. I more than
half agree that the FSR is the better choice for CPython, which had no
particular attachment to UTF-16 in the way that I think Jython, for
instance, does.
