  <p>Instead of clean uft8 i've got an html encoded char. </p>
  
  <p>What do i do wrong ?</p>
  
  <p>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</p>
  
  <p>Laravel controler (ajax get Json Data) </p>
  
  <pre><code>public function getList()
  {
      $regie = Regie::select(['id','libelle','web'])
          -&gt;where('typemedia_id', '=', 8)
          -&gt;with('grouperegies');
  
          return Datatables::make($regie)-&gt;toJson();
   }
  </code></pre>
  
  <p>Laravel Blade (view) js part</p>
  
  <pre><code>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' }
        ]
      });
    });
  
  </code></pre>
  
  <p>A dd( Datatables::make($regie)->toJson()) in my controler show me that data are already in html encode char. is it normal ? </p>
