Language broken, when get .csv file with search result, SHARE menu

Hello,
I have a problem on saving the .csv file from a search result (at discovery).
When I clicked a "share" button and try to get result as a .csv file,
it generates the .csv very well but Korean Language is broken.
What kind of solution or configuration needed to solve this?
is this ES problem or kibana problem?

Hi @suminlim,

Can you share which version of Elasticsearch and Kibana you are using? What do you mean by the Korean Language is broken? Is the data exported in English or malformed characters?

Let us know!

self. answer.
I miss understood. When I open it on the Visual Code it does not broken. but when I open it on Excel, it broken. It seems that depends on the editor(or viewer)'s encoding setting.
Thank you.

You need to send it as UTF8 to Elasticsearch.
