/**
 * When filtering a table with accented characters (letters with diacritical marks)
 * 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 a comprehensive range of letters
 * with diacritical marks to their "normalized" a..Z latin equivalents.
 *
 * This plug-in targets a wider scope of languages than the accent-neutralise plugin.
 * European languages such as slavic, nordic, baltic, finnish, celtic, albanian,
 * hungarian (etc) is covered as well as turkish and asian languages written in european latin.
 *
 * For example is the letters ＥÈÉÊỀẾỄỂẼĒḔḖĔĖËẺĚȄȆẸỆȨḜĘḘḚƐƎ searchable by the input 'E'.
 *
 * As a additional feature you can customise the plugin by allowing certain diacratics:
 *
 * jQuery.fn.DataTable.ext.type.search.allowDiacritics( array );
 *
 * For example you would like to be able filter the nordic letters æ, ø, å :
 *
 * jQuery.fn.DataTable.ext.type.search.allowDiacritics( ['æ', 'ø', 'å' ] );
 *
 *
 *  @name Diacritics-neutralise
 *  @summary Replace accented characters (diacritics) with latin equivalents
