This is a really good description of the issues involved with character sets and encodings, thanks.

You don't explain why it is important to work with encoded code points.  What's wrong with working with code points?

Again you've made the claim that the flexible string representation is a mistake.  But you haven't said WHY.  I can't tell if you are trolling us, or are deluded, or genuinely don't understand what you are talking about.

Some day you might explain yourself. I look forward to it.
