/**
 * When searching a table with accented characters, it can be frustrating to have
 * an input such as _Zurich_ not match _Zürich_ in the table (`u !== ü`). This
 * type based search plug-in replaces the built-in string formatter in
 * DataTables with a function that will replace the accented characters
 * with their unaccented counterparts for fast and easy filtering.
 *
 * Note that this plug-in uses the Javascript I18n API that was introduced in
 * ES6. For older browser's this plug-in will have no effect.
 *
 *  @summary Replace accented characters with unaccented counterparts

 *        $('#example').dataTable();
