This is just a heads up for anyone trying to release an app to Windows Store.
When you run the game in VS you will see an HTML1701 error in javascript console.
When compiled for store this will FAIL validation.
To fix:
Open jquery-2.1.1.min.js in visual studio
Select File\Save as\Save\With encoding\Unicode(UTF-8 with signature)
Rebuild the app and validation will now PASS.
This was not an issue in previous versions of C2, but with R 185.
