//! # The Unicode Library
//!
//! Unicode-intensive functions for `char` and `str` types.
//!
//! This crate provides a collection of Unicode-related functionality,
//! including decompositions, conversions, etc., and provides traits
//! implementing these functions for the `char` and `str` types.
//!
//! The functionality included here is only that which is necessary to
//! provide for basic string-related manipulations. This crate does not
//! (yet) aim to provide a full set of Unicode tables.

// Do not remove on snapshot creation. Needed for bootstrap. (Issue #22364)
