• P1628: Unicode character properties

As the author I do not expect to do further work on this in the 23 cycle

That matches my expectations, thanks for confirming.

 

Not that we have a paper, or that I'm asking for anyone to do work, but without access to the UCD, all the other algorithms are off the table. In theory it's an implementation detail, in practice it would be an ABI break to change the APIs for property lookup, and having two or more mechanisms in a std library implementation seems like a bad idea. 
Expectation setting is important. It's not clear to everyone how the Unicode layers work, even if the explanations are straight-forward. 

Clarification: i will do further work.  Just don't expect that to happen before the end of the C++23 cycle. Lewg queue is full :)

We can start to talk about it... But transcoding seems more important anyway?
