How to logging unicode dictionary from elasticsearch-py?

By default, elasticsearch-py logs output dictionary as json dumped like:

{'key': '2016\u5e747\u670829\u65e5'}

While I'd like to see the result as following:

{'key': '2016年7月29日'}

How can I do that?

EDIT

Python 2.7.10

$ pip freeze | grep elasticsearch
elasticsearch==1.9.0

Solution

elasticsearch-py package has improved the unicode logging output.
