|
* 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.
