How to properly set up locales for node.js?

Question

Node.js

Good day. The essence of the problem. I am developing an application on Nuxt.js (this is a server-side rendering for Vue) I am trying to export json to csv. When I work locally on my computer everything is fine. When I roll out on a dev server (Ubuntu 16) on a vps csv file arrives all in krakozyabah.
On dev, the application is hidden behind nginx. I suspect that something is not configured correctly on the server
. On the local machine ru_RU ru_RU.UTF-8 At the same time, in the browser, the same data that I export both on the local machine and on the server look normal.
