Answer 1

If you inject a string with unicode characters via javascript into a webpage they will be displayed the way they should automatically (given that the browser innquestion support the display of that character).

This can be seen in this example: http://jsfiddle.net/KyuKE/1/

You can read the data in a textNode by accessing it’s data property which will give you a string. This string will have the charCodeAt method available to get the charCode.

Example can be seen here: http://jsfiddle.net/KyuKE/2/

You can read the documentation for charCodeAt here: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/charCodeAt
