How to set connection charset using node-oracledb

I am trying to connect to Oracle database from node.js.

I have successfully installed the node-oracledb driver. I can connect to my Oracle database using the TNSNAMES file.

The problem is, my database is using NLS_CHARACTERSET EE8ISO8859P2 character set. In php applications I can change that to use UTF-8 while calling oci_pconnect.

Is there a way to do the same with node driver?
