Hello,

I don't know well at kibana yet. : (

I have filed which has UTF-8 urlencoded string.  
Is there a simple way to decode it on JSON Input from Kibana ?  
I have found painless script reference but didnt find proper way.

Anyone can help ?

example)

in filed query, it has utf-8 encoded korean characters like below

%EC%84%9C%EC%9A%B8%EC%84%9C%EC%B4%88%EA%B5%AC%EC%9D%B8%EB%A0%A5

in field "query", it has utf-8 encoded korean characters.

%EC%84%9C%EC%9A%B8%EC%84%9C%EC%B4%88%EA%B5%AC%EC%9D%B8%EB%A0%A5

Why is it encoded, rather than simply storing "서울서초구인력" in the field?

It is httpd's log which is not under my control.  
the filed is for request param.  
I can touch this on kibana but no right to change filebeat, elasticsearch.

Unfortunately there's not really a way to do this, but you could write a Kibana plugin that adds a custom field formatter to accomplish this.
