Let me expand on 3 of my points. First, performance == time: Point 3. You correctly identified a time regression in finding a character in a string. I saw that the slowdown was *not* inherent in the FSR but had to be a glitch in the code, and reported it on pydev with the hope that someone would fix it even if it were not too important in real use cases. Someone did. Point 1. You incorrectly generalized that extreme case. I reported (a year ago last September) that the overall stringbench results were about the same. I also pointed out that there is an equally non-representative extreme case in the opposite direction, and that it would equally be wrong of me to use that to claim that FSR is faster. (It turns out that this FSR speed advantage *is* inherent in the design.) Memory: Point 2. A *design goal* of FSR was to save memory relative to UTF-32, which is what you apparently prefer. Your examples show that FSF successfully met its design goal. But you call that success, saving memory, 'wrong'. On what basis? You *claim* the FSR is 'wrong by design', but your examples only show that is was temporarily wrong in implementation as far as speed and correct by design as far as memory goes. -- Terry Jan Reedy
