UTF-8 storage problem of Chinese ~~ garbled problem

seakey

DOM4J writes garbled files, and re-encoding does not work. I wrote a test code as follows
import java.io. *;
import org.dom4j. *;
import org.dom4j.io. *;
public class Test {
public static void main (String [] args)
    {
      try {
         SAXReader reader = new SAXReader ();
         Document document = reader.read ("c: /Demo.txt");
         Element root = document.getRootElement ();
        String a = "R & D department";
         Element newElement = root.addElement ("Department")
                  .addAttribute ("value", new String (a.getBytes (), "UTF-8"))
                      ;
        // OutputFormat format = new OutputFormat ("", true, "GBK");
       // Using format can solve the problem. However, XML is specified as UTF-8.
        XMLWriter writer = new XMLWriter (
           new FileOutputStream (new File ("c: /Demo.txt")));
          // new FileWriter ("c: /Demo.txt"));
          // Using FileWriter is not correct, DOM4J is not transcoded, it will report an error when writing the second time
                  writer.write (document);
               writer.close ();
       } catch (Exception e) {System.out.println (e.getMessage ());}

    }
}
Demo.txt
<? xml version = "1.0" encoding = "UTF-8"?>
<Company>

</ Company>

You don't need new String (a.getBytes ("GBK"), "UTF-8") a. The default output is utf-8

Change to gb2312 to try

Everyone sees the problem ...
Now the requirement is UTF-8

         Document document = reader.read ("c: /Demo.xml");
         Element root = document.getRootElement ();
        String a = "R & D Department";
        System.out.println (root.getText () + "1");
         Element newElement = root.addElement ("Department")
                  .addAttribute ("value", new String (a.getBytes ("UTF-8"), "UTF-8"))
                      ;
        OutputFormat format = new OutputFormat ("", true, "GBK");
       // Using format can solve the problem, but XML is specified as UTF-8
        XMLWriter writer = new XMLWriter (

          // new FileWriter ("c: /Demo.txt"));
          // The use of FileWriter is not correct, DOM4J has not transcoded, and it will report an error when writing the second time
                  writer.write (document);
               writer.close ();
       } catch (Exception e) {System.out.println (e.getMessage ());}

    }

Thank you LS
 Element newElement = root.addElement ("Department")
                  .addAttribute ("value", new String (a.getBytes ("UTF-8"), "UTF-8"))
                      ;
For the society, the decoding is UTF-8? a.getBytes ("UTF-8")

The above writing is actually equivalent to not writing

I just want to tell you that new String (a.getBytes (), "UTF-8"))) caused garbled characters

You first get the unicode encoding of Chinese characters, then treat this encoding as utf-8 and change it back to unicode again. Certainly not work

In fact, <? Xml version = "1.0" encoding = "UTF-8"?> Is not the encoding of xml itself,

It is to tell which code to use other software to interpret

So you do n’t need to worry too much about working with xml files locally

Thank you

<? xml version = "1.0" encoding = "UTF-8"?> Just this one should be fine
