chardet [](https://travis-ci.org/runk/node-chardet)
=====
Chardet is a character detection module for NodeJS written in pure Javascript.
Module is based on ICU project http://site.icu-project.org/, which uses character
occurency analysis to determine the most probable encoding.
## Installation
```
npm i chardet
```
## Usage
```javascript
var chardet = require('chardet');
chardet.detect(new Buffer('hello there!'));
// or
chardet.detectFile('/path/to/file', function(err, encoding) {});
// or
chardet.detectFileSync('/path/to/file');
```
## Working with large data sets
Sometimes, when data set is huge and you want to optimize performace (in tradeoff of less accuracy),
you can sample only first N bytes of the buffer:
```javascript
chardet.detectFile('/path/to/file', { sampleSize: 32 }, function(err, encoding) {});
```
## Supported Encodings:
* UTF-8
* UTF-16 LE
* UTF-16 BE
* UTF-32 LE
* UTF-32 BE
* ISO-2022-JP

* ISO-8859-2
* ISO-8859-5
* ISO-8859-6
* ISO-8859-7
* ISO-8859-8
* ISO-8859-9

Currently only these encodings are supported, more will be added soon.
