cpdetector - 編碥偵測(Java)

「cpdetector, free java code page detection.」，這是另一套編碼偵測的解決方案(Java)~ 同時也包含了Mozilla's chardet (jchardet)~

另外根據「Shared Development: Character encoding detection」所針對「cpdetector」的編碼測試~ 它所顯現的成果的確相當顯著~ 有需要的人用看看吧~

範例程式

import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.nio.charset.Charset;

import cpdetector.io.CodepageDetectorProxy;
import cpdetector.io.HTMLCodepageDetector;
import cpdetector.io.JChardetFacade;

public class CPdetector
{
	private static CodepageDetectorProxy detector = CodepageDetectorProxy.getInstance();
	
	static
	{
		detector.add(new HTMLCodepageDetector(false));
		detector.add(JChardetFacade.getInstance());
	}
	
	public String getEncoding(File f)throws Exception
	{
		return getEncoding(f.toURI().toURL());
	}
	public String getEncoding(URL url)throws IOException
	{
		Charset charset = detector.detectCodepage(url);

		if (charset != null)
			return charset.name();

		return null;
	}

	public static void main(String[] args)
	{
		CPdetector detector = new CPdetector();
		try
		{
			String encoding = detector.getEncoding(new File("Big5.txt"));
			System.out.println("encoding:"+encoding);
			encoding = detector.getEncoding(new URL("http://www.google.com.tw"));
			System.out.println("encoding:"+encoding);
		}catch(Exception e)
		{
			e.printStackTrace();
		}
	}
}

範例結果：

encoding:UTF-8
encoding:Big5
