I posted rust-lang/rust#134043 to give a mechanism to notify us when this changes. This has fallen out of date many times in the past, and I think it would be nice to avoid that. I'm not sure if that's really the best approach (I thought about using cron jobs to do it instead), but it seemed relatively easy to just add a test. |

This change happened in Rust 1.83.
As I understand it, rustc's behaviour here is determined by the versions of the
unicode-xidandunicode-normalizationcrates it's built with.These were updated to 0.2.6 and 0.1.24 respectively in
rust-lang/rust#129624
Both of those versions update their character databases to Unicode 16.0.0.
I've checked that rustc 1.83 accepts the following (which rustc 1.82 doesn't):
