lave et xml dokument med UTF-16

UTF-8 kan sagtens gemme ÆØÅ

nej desvære ikke, jeg har prøvet det og hele lortet fucker up.
UTF-8 er en standard som kun kan håndtere det engelske alfabet.

US-ASCII kan kun gemme det engelske alfabet

UTF-8 kan gemme alle unicode tegn

man skal være opmærksom på at ÆØÅ o.lign. bliver gemt som 2 bytes og et program
som fejlagtigt fortolker det som ISO-8859-1 vil derfor se sjov ud

men hvis du gerne vil gemme i UTF-16, så kan det også lade sig gøre

hvordan gemmer du dit XML dokument ?

import java.io.IOException;

import javax.xml.parsers.*;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import com.sun.org.apache.xml.internal.serialize.XMLSerializer;

public class MyXMLWriter {
       
    public void save(){
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
       
        try {
              DocumentBuilder builder = factory.newDocumentBuilder();
              Document document = builder.newDocument();
              document.setXmlStandalone(true);
              Element root = (Element) document.createElement("movies");

              document.appendChild(root);
             
              XMLSerializer serializer = new XMLSerializer();
             
              try {
                 
                serializer.setOutputCharStream(new java.io.FileWriter("C://myxml.xml"));
            } catch (IOException e) {
                e.printStackTrace();
            }
               
            } catch (ParserConfigurationException pce) {
                pce.printStackTrace();
            }
           
    }
}

forkert kode sorry.

Jeg gør det sådanne her:

prøv og erstat

serializer.setOutputCharStream(new java.io.FileWriter(des + name));

med

serializer.setOutputCharStream(new java.io.OutputStreamWriter(new java.io.FileOutputStream(des + name), "UTF-8"));

Det virkede ikke. :-)

Lukker spørgsmålet
