utf8-rune 0.0.2

Lightweight crate that aims at being a building block for libraries that work with UTF-8 data. This crate provides the struct Rune which can thought of in some cases as a drop-in replacement to Rust's char type. This crate also provides a few low-level tools to work with raw pointers of bytes and work with a sequence of bytes to produce valid UTF-8 data. The idea of Rune both borrows from and expands Golang's notion of rune such that rather than representing one 32 bits integer, each `utf8_rune::Rune` represents a set of bytes that, when displayed together represent a single visible UTF-8 character.
