Completely solve the Java character encoding problem [00 original]__ajax

Recently in the MP3 ID3 tag extraction, but also encountered the problem of encoding Chinese characters.
Remember when you read the Chinese text from a text file, the following method looks like this:


/**
* Read text file content by line
* @param fileName
* File path and filename
* @throws IOException
*/
public void ReadFile (String fileName)
{
Try
{
InputStream is = new FileInputStream (fileName);

Bytearrayoutputstream byteout = new Bytearrayoutputstream ();
byte tmp[] = new byte [1024];
BYTE context[];

Is.read (TMP);
Byteout.write (TMP);
context = Byteout.tobytearray ();
String str = new String (Context, "GBK");
System.out.println (str);
}
catch (FileNotFoundException Fnfe)
{
Fnfe.printstacktrace ();
}
catch (Exception e)
{
E.printstacktrace ();
}
}
The same approach to handling ID3 tags is problematic. New String (Context, "GBK"), out or garbled ....
consulted a variety of materials, wrote a simple solution to the test, as follows:

Package cn.edu.ynu.sei.liva.test;

public class Charsetdecoder
{
public static void Main (string[] args)
{
Try
{
String musicname = "Óâ¸òµäðä";
System.out.println ("Before decoding:" + musicname);
1. Turn musicname (press unicode->iso-8859-1) back to the original byte[].
2. Because the original song name is GBK encoding way, so put bytes[] according to the Gbk->unicode Way of transcoding
String musicnamedecode = new String (Musicname.getbytes ("iso-8859-1"), "GBK");
System.out.println ("After decoding:" + Musicnamedecode);
}
catch (Exception e)
{
E.printstacktrace ();
}
}
}

Oh, finally can completely solve the Java character coding problem.
