# utf8proc

|
|
|
|
|
|
[utf8proc](http://julialang.org/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) by 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
|
|
the included `LICENSE.md` file for more detailed information.
|
|
|
|
## 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 supported is 9.0.0.
|
|
|
|
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.
