文本文件的字符编码检测

从代码看，是基于频率分析，还是比较准确的。 
测试代码如下：

import java.io.File;  
import java.io.UnsupportedEncodingException;  
import java.net.MalformedURLException;  
import java.net.URL;  
  
public class Test {  
  public static void main(String[] args) throws UnsupportedEncodingException, MalformedURLException {  
    BytesEncodingDetect s = new BytesEncodingDetect();  
    String str = "??¤¤¤å";  
    System.out.println(BytesEncodingDetect.nicename[s.detectEncoding(str.getBytes("ISO-8859-1"))]);  
    System.out.println(new String(str.getBytes("ISO-8859-1"), "BIG5"));  
    System.out.println(BytesEncodingDetect.nicename[s.detectEncoding("Java世界".getBytes())]);  
    System.out.println(BytesEncodingDetect.nicename[s.detectEncoding(new URL("http://www.iteye.com"))]);  
    System.out.println(BytesEncodingDetect.nicename[s.detectEncoding(new File("src/Test.java"))]);  
  }  
}  

 

输出结果:

Big5  
??中文  
GB-2312  
UTF-8  
UTF-8
