# uchardet

[uchardet](https://www.freedesktop.org/wiki/Software/uchardet/) is an encoding detector library, which takes a sequence of bytes in an unknown character encoding without any additional information, and attempts to determine the encoding of the text. Returned encoding names are [iconv](https://www.gnu.org/software/libiconv/)-compatible.

uchardet started as a C language binding of the original C++ implementation of the universal charset detection library by Mozilla. It can now detect more charsets, and more reliably than the original implementation.

The original code of universalchardet is available at http://lxr.mozilla.org/seamonkey/source/extensions/universalchardet/

Techniques used by universalchardet are described at http://www.mozilla.org/projects/intl/UniversalCharsetDetection.html

## Installation

### Debian/Ubuntu/Mint

    apt-get install uchardet libuchardet-dev

### Mageia

    urpmi libuchardet libuchardet-devel

### Fedora

    dnf install uchardet uchardet-devel

### Gentoo

    emerge uchardet

### Mac

    brew install uchardet

### Windows

Binary packages are provided in Fedora and Msys2 repositories. There may
exist other pre-built packages but I am not aware of them.
Nevertheless the library is very easily and quickly compilable under
Windows as well, so finding a binary package is not necessary.
Some did it successfully with the [CMake Windows
installer](https://cmake.org/download/) and MinGW. It should be possible
to use MinGW-w64 instead of MinGW, in particular to build both 32 and
64-bit DLL libraries).

Note also that it is very easily cross-buildable (for instance from a
GNU/Linux machine).

### Build from source

Releases are available from:
https://www.freedesktop.org/software/uchardet/releases/

If you prefer a development version, clone the git repository:

    git clone https://gitlab.freedesktop.org/uchardet/uchardet.git

The source can be browsed at: https://gitlab.freedesktop.org/uchardet/uchardet

    cmake .
    make
    make install

### Build with flatpak-builder

Here is a working "module" section to include in your Flatpak's json manifest:

```
"modules": [
    {
        "name": "uchardet",
        "buildsystem": "cmake",
        "builddir": true,
        "config-opts": [ "-DCMAKE_INSTALL_LIBDIR=lib" ],
        "sources": [
            {
                ...
            }
        ]
    }
]
```
