I have several files containing the results of an ItemSearchRequest at
Amazon.com.
Most files are 100-200kB XML files, which are, according to the XML
declaration, UTF-8 encoded.

I read the file from Amazons REST interface (target is the url which
responds with the XML file):

  Reader reader = new InputStreamReader(url.openStream());
  BufferedReader bufferedreader = new BufferedReader(reader);
  StringBuffer sb = new StringBuffer();  
  while (((c = bufferedreader.read()) != -1) && (c != 0)) {

          sb.append((char)c);
       }
  result = sb.toString();

The string "result" will then be written into a RandomAccessFile.

Yet when I try to build a JDOM Document from the file using

 Document doc = builder.build(file);

I keep getting a JDOMParseException for some of the files. Reason: The file
apparently contains non UTF-8 characters.

Question: How can I get the SAXBuilder to ignore those characters? Does
anybody know the reason why those characters even appear every once in a
while?

Below is the first part of the exception I mentioned.

Thanks

Matt
