Ah, there's already a PR for unicode version bump in #14. I'll drop that commit from mine then. |

Found this when investigating compile time for RustPython. Looks like SimonSapin has transferred the project to unicode-rs. @Manishearth, does this change seem reasonable to you? |

@Manishearth, thanks for the suggestion. I can't edit this pr, so created #21 with a workflow. Verified it by manually messing up the file on my own branch: https://github.com/crazymerlyn/rust-caseless/actions/runs/12504550179 |

regexis a pretty slow dependency to build (well,regex-syntaxis anyway), and it's pretty unnecessary for this crate to generate the table each time it builds.I did this by just moving your build.rs to its own crate, which dumps the table to stdout (because it's easy, flexible, but mostly harder to mess up than taking a file argument. Although if you'd rather I do that, I can).
For clarity,
cargo run -p print-table > src/case_folding_data.rscan update the pre-generated table.Oh, also I updated you to unicode 13.0.0. I did it just because seems like good manners to do so when I'm updating the tables anyway, but I can undo it if you'd prefer.
