字符串编码探测、转换的使用

由于工作的关系，常常需要获取某段字符串的编码信息，防止乱码出现。在网上找了一下，有下面几个库

1.C#

https://code.google.com/p/ude/  探测库

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

2.Java

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

3.Python
     http://chardet.feedparser.org/

4.C++

IBM有一个开源库ICU，http://site.icu-project.org/  转换

Linux

enca:         http://freecode.com/projects/enca 探测和转换库

Mozilla 编码的c++版本

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);
        }
