Java, XML DocumentBuilder - setting the encoding when parsing

I solved it, given alot of trial and errors.

I was using OutputFormat format = new OutputFormat(document);
but changed it to OutputFormat format = new OutputFormat(d, encoding, true);
and this solved my problem.

encoding is what I set it to be
true refers to whether or not indent is set.

Note to self - read more carefully - I had looked at the javadoc hours ago - if only I'd have read more carefully.

// Read XML
String xml = "xml"
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new InputSource(new StringReader(xml)));

// Append formatting
OutputFormat format = new OutputFormat(document);

if (document.getXmlEncoding() != null) {
  format.setEncoding(document.getXmlEncoding());
}

format.setLineWidth(100);
format.setIndenting(true);
format.setIndent(5);
Writer out = new StringWriter();
XMLSerializer serializer = new XMLSerializer(out, format);
serializer.serialize(document);
String result = out.toString();
