//! # 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.

/// Character manipulation (`char` type, Unicode Scalar Value)
///
/// This module provides the `Char` and `UnicodeChar` traits, as well as their
/// implementation for the primitive `char` type, in order to allow basic character
/// manipulation.
///
/// A `char` actually represents a
/// *[Unicode Scalar Value](http://www.unicode.org/glossary/#unicode_scalar_value)*,
/// as it can contain any Unicode code point except high-surrogate and
/// low-surrogate code points.
///
/// As such, only values in the ranges \[0x0,0xD7FF\] and \[0xE000,0x10FFFF\]
/// (inclusive) are allowed. A `char` can always be safely cast to a `u32`;
/// however the converse is not always true due to the above range limits
/// and, as such, should be performed via the `from_u32` function..
