-//! # 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.
