In Node.js, save JavaScript String as a UTF-8 encoding file in Parse.File system (parseplatform)

stringToUTF8ParseFile.js

const e = require('text-encoding'); //it is built-in for some browsers. We neeed to install it in Node.js
const uint8array = new e.TextEncoder().encode(stringData);
const normalArray = Array.prototype.slice.call(uint8array); 

// http://docs.parseplatform.org/js/guide/#creating-a-parsefile
const file = new Parse.File(fileName, normalArray);  
file.save().then(function() {
  // The file has been saved to Parse.
}, function(error) {
  // The file either could not be read, or could not be saved to Parse.
});
