I would have the knives blades chart a little earlier, and make it very obvious that each character shares a code point (maybe have a code point column) and talk about in the text that yes, this is weird. 3 visually distinct Unicode characters share a single code point. For me this was very hard to wrap my head around the first time I encountered the problem. Maybe other people find it hard to understand in different ways. I believe that Unicode even claims that distinctly looking characters are to have their own code points, but similarly looking characters should share a code point (e.g, there is no French a and English a, even though they are pronounced differently. And Danish ø and Swedish ö are pretty much the same pronunciation but differently written, so they don’t share a code point.)
