Error running in Node 5.9.1

[burnnat]

The package.json indicates that Node.js is supported back to version 4.2:

  "engines": {
    "node": ">=4.2.0"
  },

However, attempting to run with node 5.9.1 I get the following error:

TypeError: utf8 is not a function

The problematic change appears to be this commit, as Buffer.from(string[, encoding]) was only introduced in Node 5.10.0.

Feel free to update the package.json 👍

Well given I'm locked into this version of node for the time being (not of my own choice), I was hoping there would be a way to maintain compatibility... 😐

That said, I'm happy to update the package.json if 5.9 is too old for support at this point.

You could replace Buffer.from with https://www.npmjs.com/package/buffer-from instead, if you'd like to submit that PR.

Edit: Unfortunately there's no type definition for it though.

I've submitted typings for buffer-from in DefinitelyTyped#26602 and will create a PR for the change here once they make it into NPM.
