How to read a text file in nodeJs if you don't know its encoding?

Question

Node.js

You need to read the contents of a plain text file (.csv). The problem is that the files come from different platforms and in different encodings (UTF-8, UTF-16, Windows 125x, etc.). And when using it, FS.readFileSuncyou must specify the encoding explicitly. And if the file is different, then the contents of the file break.

Answer 1

when using FS.readFileSunc, you must specify the encoding explicitly

It is not true.
