[utf8proc](https://github.com/JuliaLang/utf8proc) is a small, clean C
library that provides Unicode normalization, case-folding, and other
operations for data in the [UTF-8
encoding](http://en.wikipedia.org/wiki/UTF-8). It was [initially
developed](http://www.public-software-group.org/utf8proc) from Jan
Behrens and the rest of the [Public Software
Group](http://www.public-software-group.org/), who deserve *nearly all
of the credit* for this package. With the blessing of the Public
Software Group, the [Julia developers](http://julialang.org/) have
taken over development of utf8proc, since the original developers have
moved to other projects.
(utf8proc is used for basic Unicode
support in the [Julia language](http://julialang.org/), and the Julia
developers became involved because they wanted to add Unicode 7 support and other features.)
(The original utf8proc package also includes Ruby and PostgreSQL plug-ins.
We removed those from utf8proc in order to focus exclusively on the C
library for the time being, but plan to add them back in or release them as separate packages.)
The utf8proc package is licensed under the
free/open-source [MIT "expat"
license](http://opensource.org/licenses/MIT) (plus certain Unicode
data governed by the similarly permissive [Unicode data
license](http://www.unicode.org/copyright.html#Exhibit1)); please see

## Quick Start ##
For compilation of the C library run `make`.
## General Information ##
The C library is found in this directory after successful compilation
and is named `libutf8proc.a` (for the static library) and
`libutf8proc.so` (for the dynamic library).
The Unicode version being supported is 7.0.0.
For Unicode normalizations, the following options are used:
* Normalization Form C: `STABLE`, `COMPOSE`
* Normalization Form D: `STABLE`, `DECOMPOSE`
* Normalization Form KC: `STABLE`, `COMPOSE`, `COMPAT`
* Normalization Form KD: `STABLE`, `DECOMPOSE`, `COMPAT`
## C Library ##
The documentation for the C library is found in the `utf8proc.h` header file.
`utf8proc_map` is function you will most likely be using for mapping UTF-8
strings, unless you want to allocate memory yourself.
