Search name with apostrophe inside mysql datatable.

Hi,
i'm using datatable plugin and works well except when i try to search records that contains apostrophs.
The problem is that the
$requestData['search']['value'])
doesn't pass the apostroph from the ajax function i have in the master file...

This is the code in the master page:

            $(document).ready(function() {
            
                    $.fn.dataTable.moment( 'DD/MM/YYYY');
                $("#search").html($("#search").html().replace(/’/g, '''));
                    var dataTable = $('#<? echo $sezione; ?>-grid').DataTable( {
                 language: { search: "Cerca" ,
                            "info": "Comuni in elenco: _TOTAL_",
                            "sLengthMenu": "Mostra _MENU_  Comuni per pagina",
                           paginate: {
                           "next": "<i class='fas fa-arrow-alt-circle-right'></i>",
                           "previous": "<i class='fas fa-arrow-alt-circle-left'></i>",
                           }
                           },
                    "processing": true,
                    "serverSide": true,
                    "stateSave": false,
                    "searching": true,
                      
                    "ajax":{
                        url :"<? echo $sezione; ?>-grid-data.php", // json datasource
                        type: "post", // method  , by default get
                        error: function(){  // error handling
                            $(".<? echo $sezione; ?>-grid-error").html("");
                            $("#<? echo $sezione; ?>-grid").append('<tbody class="<? echo $sezione; ?>-grid-error"><tr><th colspan="3">Nessun dato presente.</th></tr></tbody>');
                            $("#<? echo $sezione; ?>-grid_processing").css("display","none");
                            
                        }
                    }
                } );
    
    
        });

any help for me?
Thanks in advance
