public class UTF8OutputStreamWriter
extends Writer

This class is used to write a stream of chars as a stream of bytes using the UTF8 encoding. It assumes that the underlying output stream is buffered or does not need additional buffering.

It is more efficient than using a OutputStreamWriter because it does not need to be wrapped in a BufferedWriter. Creating multiple instances of BufferedWriter has been shown to be very expensive.
