This repository hosts a project to define a text format called [Basic Text], a
subset of Unicode that focuses on *text*: it excludes unprintable control
characters, characters which depend on out-of-band information to interpret,
non-characters, deprecated characters, and more, while aiming to preserve
everything of practical use to plain text and formats built on top of it. See
the [Book] for more information.

It also includes a Rust crate which aims to implement the Basic Text format,
providing several utilities:

 - [`TextString`] and [`TextStr`] are similar to the standard library's
   [`String`] and [`str`], but use the Basic Text string format, along with a
   [`text!("...")` macro] for Basic Text string literals.

 - [`TextReader`] and [`TextWriter`] are input and output streams which use the
   Basic Text stream format. On input, content is converted in a way which is
   lossy with respect to the original bytestream. Output uses the "strict"
   conversion method, in which invalid content is diagnosed with errors.

 - [`BufReadText`], an extension trait that adds [`text_lines`] and
   [`text_lines_lossy`] to [`BufRead`] implementations for reading lines
   from an input stream as `BasicText` strings.

 - [`TextDuplexer`] is a [`Duplex`] for reading and writing on an interactive
   stream using Basic Text.

The code here is usable, and implements everything in the [Basic Text] spec,
but is not very mature or optimized yet.
