How to do utf-8 encoding in node js

Question

I am trying to do UTf 8 encoding to a string in node js

I have tried Buffer(someString, 'utf8') and also the package utf8 but it is always returning me the original string. var utf8 = require('utf8');

function decrypt(enc) {
  console.log('type', typeof enc);
  enc = utf8.encode(enc);
  console.log('encoding', enc);
  return enc;
}

console.log('decrypted:', decrypt('message'));

I used 'message' string in this https://mothereff.in/utf-8 and the desired result is not coming as expected. How do we do the encoding?

Try to do it like this using the Buffer.from method, then the encoded string is converted back to a string using the buffer.tostring('utf8') method:

      function codUtf8(str) {
        const buffer = Buffer.from(str, 'utf8');
        const strCod = buffer.toString('utf8');
        return strCod;
       }

console.log(codUtf8('message')

);
