XML data - charset encoding problem

Question

Hello all,
  I am facing an issue on charset encoding. My requirement is to send an XML and read the the output XML to display the output. The output XML is encoded in "ISO-8859-1" and we are retrieving/reading it in "UTF-8". But some special characteres in the output XML are appearing as it is.
  Could some one let me know on how to obtain the desired characters.
Code snippet while reading the XML:
BufferedReader inStream = null;
BufferedWriter outStream = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream(),"UTF-8"));
inStream =
     new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
Thanks & regards,
Sharath

Hi Sharath,
To read the XML file use the following. Don’t mention the character set during reading it.I hope it will help you.
XML file(emp.xml)
<?xml version="1.0" encoding="ISO-8859-1"?>
<Emp>
<EmpDetails>
       <firstname>Sarbari</firstname>
       <lastname>Saha</lastname>
  </EmpDetails>
  <EmpDetails>
       <firstname>Tumpa</firstname>
       <lastname>Hazra</lastname>
  </EmpDetails>
</Emp>
