    Google Drive File Picker Example

This is an example of how to use the Google Drive file picker and Google Drive API to retrieve
files from Google Drive using pure JavaScript. At the time of writing (14th July 2013), Google have
good examples for using these two APIs separately, but no documentation on using them together.
Note that this is just sample code, designed to be concise to demonstrate the API. In a production
environment, you should include more error handling.
See a demo at http://stuff.dan.cx/js/filepicker/google/

Sometimes, unicode symbols that have to be inserted in an HTML page should be escaped.
For example, everybody know, that’s “&” should be escaped as “&”, ” ” as “ ” and so on.
But what, if you should insert symbol, that you never used before. So you don’t know how it should be present or escaped.
Code below, helps you to get valid decimal unicode for appropriate symbol.
