##Usage

Import the library:

using Chartect.IO;

you can feed a StreamDetector to the detector:

using System.IO;
using Chartect.IO;

public class program
{
    public static void Main(String[] args)
    {
        var filename = args[0];
        var detector = new StreamDetector();
        using (FileStream stream = File.OpenRead(filename)) 
        {
            detector.Read(stream);
            detector.DataEnd();
            if (detector.Charset != null) 
            {
                Console.WriteLine("Charset: {0}, confidence: {1}", detector.Charset, detector.Confidence);
            }  
            else  
            {  
                Console.WriteLine("Detection failed.");  
            } 
        }
    }
}

or use StringDetector. StringDetector assumes that there is only one string (so you don't have to call DataEnd):

    var detector = new StringDetector();
    var input = "ðÏÓÌÅ ÏËÏÎÞÁÔÅÌØÎÏÇÏ ÒÁÚÏÒÅÎÉÑ ÏÔÃÁ ÓÅÍÅÊÓÔ×Á";

    detector.Read(input);

    if (detector.Charset != null) 
    {
        Console.WriteLine("Charset: {0}, confidence: {1}", detector.Charset, detector.Confidence);
    }  
    else  
    {  
        Console.WriteLine("Detection failed.");  
    }  

You can also use ArrayDetector to take in an array of bytes.

Chartect.IO is a fork of the UDE C# port of Mozilla Universal Charset Detector by Rudi Pettazzi from https://code.google.com/p/ude/.

This work was based on the original source code from Mozilla available at:

http://lxr.mozilla.org/mozilla/source/intl/chardet/src/

The article "A composite approach to language/encoding detection" describes the algorithms of Universal Charset Detector and is available at:

http://www-archive.mozilla.org/projects/intl/chardet.html

Some data-structures used into this port have been adapted from the Java port "juniversalchardet", available at:

http://code.google.com/p/juniversalchardet/

Also there is "chardet" (in Python) available at:
