Subject Help with encoding issue.
Date Tue, 03 Apr 2012 22:22:26 GMT
Hi, I noticed that String Serializer somehow doesn't do well encoding
special characters such as "ü".

I tried to create a ByteBufferEncoder this way:

import java.nio.ByteBuffer;

import kafka.message.Message;

import kafka.serializer.Encoder;


public class ByteBufferEncoder implements Encoder<ByteBuffer> {

   public Message toMessage(ByteBuffer buffer) {

     return new Message(buffer);

   }

}


but I get this exception [1]


Could you guys please advice on how to fix my encoding issue?

Thanks
