/**
 * 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.
