JSON.stringify outputing wrong the ' character

Right, OK, let me jump ahead and say that by default JSON is not included in ExtendScript. Meaning, that it does not exist out of the box in ExtendeScript.

However, if you are still able to use JSON without specifically including it yourself, then this means that some other third tool is modifying global space and injecting JSON into the app. This is bad, and you should never rely on this.

If you need to use JSON in your script, you should always include it yourself:

1. Download this https://github.com/douglascrockford/JSON-js/blob/master/json2.js?

2. Then in your JSX file use include to load JSON into your local script scope: #include 'path/to/json2.js'

So now you end up with the JSON version that you can control, without relying on JSON injected by accident by third parties.
