Just wanted to drop a note here that the Unicode crates that are part of https://github.com/open-i18n/rust-unic are unmaintained.

https://rustsec.org/advisories/RUSTSEC-2025-0083.html

This got flag in our project hyperlight-dev/hyperlight#987 by some automation and I tracked it down here.

It suggests using https://crates.io/crates/icu_properties.
