That’s a pretty harsh comparison. It’s a fairly simple encoding which is UTF-8 compatible and allows codepoints to be arbitrarily large. It’s a real encoding

That’s a pretty harsh comparison. It’s a fairly simple encoding which is UTF-8 compatible and allows codepoints to be arbitrarily large. It’s a real encoding proposal with a simple rigorous specification. I don’t have a use case for needing arbitrarily large codepoints, but for people who do, this makes more sense than hacks such as having surrogates in Unicode’s hi-bit private use area.
