This would mean the "original version of Charles" died in the process.
But in *that* sense the "original version of Charles" dies every instant.

Why are you saying the use of "I" was incorrect. The term "I" is an
indexical: its *meaning* remains the same although its *reference* can
change according to the locutor using it. (Similar things happens for
different indexical terms like "now", "modern", "current", "artificial",
Now, both with MWI or even just comp, we learn that I, actually any "Is",
differentiate(s) all the time. This does not change the meaning of "I" but
entails the possibility of multiplying its references.
That's hardly new, amoeba does that since a long (earth) time.

There exists computer science tools for defining "self" and making precise
the meaning of "I" by finitely describable entities, including their
possible contextually dependent references.
Such tools relies on diagonalisation.
Perhaps you can look at
(or wait patiently for diagonalisation 2 on the parallel list!).
