The point is that "folding", by its very definition, means mapping distinct things to the same value. So no one argues that the letters are different before they are folded. > Seriously, if you want a feature for the people who think on terms of > encodings, that's fine, but please keep in mind that most people see > text as text, the same thing they can write with a pencil, not series of > bytes on Unicode, ASCII or whatever. The notion of "text" moved a long way since we were in kindergarten. The Unicode Standard is about plain text, not anything else. We slowly adapt to that, and character folding is one milestone on that long journey. It has nothing to do with encoding.
