DESCRIPTION

Ude is a C# port of Mozilla Universal Charset Detector.

The original source code is available at: 

http://mxr.mozilla.org/mozilla/source/extensions/universalchardet/src/    

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

    http://www.mozilla.org/projects/intl/UniversalCharsetDetection.html
    http://mxr.mozilla.org/mozilla-central/source/extensions/universalchardet/doc/UniversalCharsetDetection.doc

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

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

Another port I know of is "chardet" (in Python) available at: 

    http://chardet.feedparser.org/

USAGE

Import the library:

    using Ude;

and feed a stream or a byte array to the detector. Call DataEnd to notify the detector that 
you want back the result:

    ICharsetDetector cdet = new CharsetDetector();
    byte[] buff = new byte[1024];
    int read;
    while ((read = stream.Read(buff, 0, buff.Length)) > 0 && !done) {
        cdet.Feed(buff, 0, read);
    }
    cdet.DataEnd();
    Console.WriteLine("Charset: {0}, confidence: {1}, cdet.Charset, cdet.Confidence);

Alternatively, you can feed a Stream to the detector:

    using (FileStream fs = File.OpenRead(filename)) {
        ICharsetDetector cdet = new CharsetDetector();
        cdet.Feed(fs);
        cdet.DataEnd();
        Console.WriteLine("Charset: {0}, confidence: {1}, cdet.Charset, cdet.Confidence);
    }    

Or you can provide an alternative implementation of the interface - Ude.ICharsetDetector - 
that wraps the original nsUniversalDetector API.
