Html charset code in inline editor in datatables/editor

I'm using datatables.net and its plugin Editor I'm having trouble when i edit a field.

in edit field i've got L& #0039;ALSACE instead of L'ALSACE

Exemple

Instead of clean uft8 i've got an html encoded char.

What do i do wrong ?

Laravel is 6.5.0. MySQL db is utf8mb4, collation utf8mb4_unicode_ci; laravel database config file is well configured ('charset' =>'utf8mb4', 'collation' =>'utf8mb4_unicode_ci') Editor is version 1.9.2 Datatables is version 1.10.20 yajra/laravel-datatables-oracle v9.7.1

Laravel controler (ajax get Json Data)

public function getList()
{
    $regie = Regie::select(['id','libelle','web'])
        ->where('typemedia_id', '=', 8)
        ->with('grouperegies');

        return Datatables::make($regie)->toJson();
 }

Laravel Blade (view) js part

var editor;
  $(document).ready( function () {
    editor = new $.fn.dataTable.Editor( {
    ajax:  '{{ url('regiepqr-list') }}',
    table: '#laravel_datatable',
    idSrc:  'id',
    fields: [
        { label: 'id', name: 'id' }, 
          { label: 'libelle', name:'libelle'},
          { label: 'web', name:'web'}
    ]
} );
$('#laravel_datatable').on( 'click', 'tbody td:not(:first-child)', function (e) {
        editor.inline( this );
    } );
$('#laravel_datatable').DataTable({
      processing: true,
      serverSide: true,
      responsive: true,
      select: true,
      dom: 'Bfrtip',
      buttons: [
        { extend: 'create', editor: editor },
        { extend: 'edit',   editor: editor },
        { extend: 'remove', editor: editor }
    ],
      language: {"url": "https://cdn.datatables.net/plug-ins/1.10.20/i18n/French.json"},
      ajax: "{{ url('regiepqr-list') }}",
      columns: [
          { data: 'id' }, 
          { data: 'libelle'},
          { data: 'web' }
      ]
    });
  });

A dd( Datatables::make($regie)->toJson()) in my controler show me that data are already in html encode char. is it normal ?

Many thank's B.
