[rabbitmq-discuss] JSON Data to be send between Java Producer and Python Consumer

[Gavin M. Roy]

To add to this the consumer probably needs to use json.loads(value, ensure_ascii=False) (not the default value for ensure_ascii) to allow it to decode UTF-8 in a JSON string.

Then you could try to really fix the problem by getting the java side to encode unicode as ascii rather than utf8 (you will see '\unnnn' strings in the output). I don't know how to do that.
