i hope so too, but UTF-16 being used by languages such as java and javascript makes me fear it might be here to stay.... i hope im wrong

The number of glyphs available by adding additional bytes drops exponentially because each subsequent byte has one less bit available.

So I think if we ever were in a situation where > 1 million code points isn’t enough, then we should look at an entirely new way to serialise those code points.

I don't quite get it. 5-byte utf-8 encoding gets extra 5 bits compared to 4 byte, and 6-byte gets extra 10 bits. If you were thinking about bits in leading byte, then yes, you are losing one bit for every extra trailing byte, but you also get 6 bits from it. So adding a byte gives you extra 5 bits.

Yeah, you’re right. I might have attempted to do mental arithmetic before coffee…
