<pre>* Unicode 8 has 2,518 `ID_Start` symbols; Unicode 9 has 2,669, i.e. 151 more (no removals).
* Unicode 8 has 109,830 `ID_Continue` symbols; Unicode 9 has 117,007, i.e. 7,177 more (no removals).
E.g. these should not throw per Unicode 9:
Function('var \u{1E943}'); // new ID_Start
Function('var _\u{1E959}'); // new ID_Continue
I’ve attached `results.js` which contains the full list of new `ID_Start` and `ID_Continue` symbols in Unicode 9, and the Node.js script used to generate it.</pre>
