+/**
+ * When search 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 remove replace the accented characters
+ * with their unaccented counterparts for fast and easy filtering.
+ *
+ * Note that with the accented characters being replaced, a search input using
+ * accented characters will no longer match. The second example below shows
+ * how the function can be used to remove accents from the search input as well,
+ * to mitigate this problem.
+ *
+ *  @summary Replace accented characters with unaccented counterparts
+ *  @name Accent neutralise

+ *  @example
+ *    $(document).ready(function() {
+ *        $('#example').dataTable();
+ *    } );

+ *  @example
+ *    $(document).ready(function() {
+ *        var table = $('#example').dataTable();
+ *
+ *        // Remove accented character from search input as well
+ *        $('#myInput').keyup( function () {
+ *          table

+ *              jQuery.fn.DataTable.ext.type.search.string( this.value )
