use-case for this code, please feel free to open an issue. Simple PRs will
still be read, and possibly accepted._

Attempts to detect the character encoding of raw text using the `uchardet`
library.

Example:

```rust
// At the top of the file.
extern crate uchardet;
use uchardet::detect_encoding_name;

// Inside a function.
assert_eq!("UTF-8",
           detect_encoding_name(""©français"".as_bytes()).unwrap());
```

If you also would also like to detect the language used in the decoded
text, see [rust-cld2](https://github.com/emk/rust-cld2).

### Getting uchardet (usually optional)

If you wish, you may install `uchardet` using your system package manager.
For example, under Ubuntu, you can run:

```sh
sudo apt-get install libuchardet-dev
```

If you skip this step, Cargo will attempt to compile `uchardet` from the
bundled source code instead.  This should work if you have an appropriate
`g++` (or MSVC) compiler installed, as well as `cmake`.  We test this build
on Linux, OS X and Windows (both MinGW and MSVC) using Travis CI.

### Contributing

As always, pull requests are welcome!  Please keep any patches as simple as
possible and include unit tests; that makes it much easier for me to merge
them.

If you want to get the C/C++ code building on another platform, please see
`uchardef-sys/build.rb` and [this build script guide][build-script].
You'll probably need to adjust some compiler options.  Please don't
hesitate to ask questions; I'd love for this library to support more
platforms.

Contributors include:

- Boris-Chengbiao Zhou.  Support for newer upstream `uchardet` libraries
  and Microsoft Windows, plus the error-chain conversion.
- Wesley Moore. Fixes for Rust beta 2 and OS X.

Thank you very much for your contributions!
