[TheFinnishOne]

when trying to build with cargo build --release, it fails to compile to 9 "unicode codepoint changing visible direction of text present in literal" errors.

here is the entire log I get when attempting to build

[xXFiEsTaDeAmOnXx]

For Rust versions ≥ 1.89.0, the lint text_direction_codepoint_in_literal must be applied at the crate level (Rust PR #141004).

This crate currently does not set the attribute, so compilation fails when string literals contain invisible Unicode directional characters.

Workarounds:

• Quick fix: Compile with Rust 1.88.0 or lower.
• Long-term fix: Add the following at the top of the crate root

#![allow(text_direction_codepoint_in_literal)]

[Kirottu]

Fixed with #229

[SBhojani]

It's still/again failing with same/similar errors at https://hydra.nixos.org/build/305729834/nixlog/1 .

[eclairevoyant]

fixed in NixOS/nixpkgs#437491 (which literally just pulls in the changes after #229)
