Writing UTF-8 XML files with Java

I had a method to write XML files with FileWriter but discovered when I wanted to (...allow my customers to...) use special characters it fell over. I needed to use a FileOutputStream in order to deal with bytes.

Original method:

 
public void oldWriteXML() throws Exception{
        storeDoc.normalize(); //storeDoc is type Document
        if (storeFile!=null){
            storeFile.delete(); //delete the old file to overwrite
        }
        OutputStreamWriter fos = new FileWriter(filename);

        OutputFormat format = new OutputFormat(storeDoc);
        format.setLineWidth(65);
        format.setIndenting(true);
        format.setIndent(2);
        XMLSerializer serializer = new XMLSerializer(fos, format);
        serializer.serialize(storeDoc);

        fos.close();
    }

New method to allow UTF-8:

 
public void writeXML() throws Exception{
        storeDoc.normalize();
        if (storeFile!=null){
            storeFile.delete();
        }
        OutputStreamWriter fos = 
                new OutputStreamWriter(new FileOutputStream(filename),"UTF-8");
        
        OutputFormat format = new OutputFormat(storeDoc, "UTF-8", true);
        format.setLineWidth(65);
        format.setIndent(2);
        
        XMLSerializer serializer = new XMLSerializer(fos, format);
        serializer.serialize(storeDoc);

        fos.close();        
    }
