>- utf8 library accepts codepoints up to 2^31

Interesting. Didn't Unicode restrict UTF-8 to allow encoding only 21 bits? Does it mean that it can now do 6 byte UTF-8 encodings? What kind of restrictions did it have before?

Comparing the documentation seems to verify this easily:

- https://www.lua.org/manual/5.3/manual.html#6.5

- https://www.lua.org/work/doc/manual.html#6.5

I don't see how this is a good change, it's like, back to 1994 utf-8
