/**
 * jQuery Breakly plugin - Breaks your texts. Gently.
 * This plugin can be used to give the browser an "hint" on when (and eventually how) break
 * some long texts that are wrapped in a container with an explicitely defined width.
 * It works adding a "special" unicode character after the given number of characters.
 * By default the plugin inserts U+200B (the zero width space), but you can specify any
 * other character as the second parameter
 *
