Google Chrome Developers says:

The new WOFF 2.0 Web Font compression format offers a 30% average gain over WOFF 1.0 (up to 50%+ in some cases). WOFF 2.0 is available since Chrome 36 and Opera 23.

Some examples of file size differences: WOFF vs. WOFF2

/**
 * Create a Tracker module for Google Analytics
 *
 * This tracker enables to track clicks on links and submits on forms. Usually
 * these events will not be recorded as the window.location is changed and the
 * request to Google Analytics is cancelled. This module prevents default
 * behaviour, tracks the Google Analytics event and then continues the link/submit.
 *
 * Data attributes are used to augment the event with category/action/label values.
 * Use them as "data-track-category", "data-track-action" and "data-track-label".
