Convert String from UTF-8 to IsoLatin1

Question

Hi everyone !
I'm trying to convert a String from utf-8 to IsoLatin1, but i got somt problems.... I'm using
actually this code, but it won't work...
I'm getting a utf-8 html String with some data and i will write it down in latin1 to a text file
String newString = new String(oldString.getBytes("UTF-8"), "ISO-8859-1");If i'm now writing this newString to a TextFile it contains cryptic signs like
& # 1 3 ; or & # 1 3 7 ; or & # 1 2 8 ;(i separated this chars)
can anyone tell me where is my fault and how can i solve this problem ?
Thanks a lot

Answer 1

Yes its XML, i got a web editor where i can add input (utf-8) and i want to write it down in my class to a xml file (isoLatin1).
My code looks likte this
     public static void setEditFragment(String content, String xPath) throws Exception {
         DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
         DocumentBuilder builder  = factory.newDocumentBuilder();
         Document document = builder.parse("3001300.xml");
         XPath xpath = XPathFactory.newInstance().newXPath();
         Node node = (Node)xpath.evaluate(xPath, document, XPathConstants.NODE);
        Charset charset = Charset.forName("ISO-8859-1");
        CharsetEncoder encoder = charset.newEncoder();    
        ByteBuffer buf = encoder.encode(CharBuffer.wrap(content));
        node.setTextContent(buf.toString()); 
           // Use a XSLT transformer for writing the new XML file
        Transformer transformer = TransformerFactory.newInstance().newTransformer();
         DOMSource        source = new DOMSource( document );
         FileOutputStream os     = new FileOutputStream("tmp.xml");
         StreamResult     result = new StreamResult( os );
         transformer.transform( source, result ); 
     }The example from http://www.exampledepot.com/egs/java.nio.charset/ConvertChar.html looks great, but if I add my own input string i get a exception that looks like this
java.nio.charset.UnmappableCharacterException: Input length = 1
     at java.nio.charset.CoderResult.throwException(Unknown Source)
     at java.nio.charset.CharsetEncoder.encode(Unknown Source)
     at HagerAbs.setEditFragment(HagerAbs.java:91)
     at HagerAbs.main(HagerAbs.java:108)When i write my input to the xml file it doesnt look like xml at all, it looks more like
<synthese>& # 13;
& # 13;
& lt;br/& gt;& # 13;
& lt;img class="thumb" src="http: ......{code}
(i seperated the char so you can see)
and this is not what i expected... how can i write it down correctly ?
