title: How can i search strange characters in Laravel?
body: <p>I have a problem with the search on my site. I have a search input to find products by name. If I type 'leña' (the problem is the strange characters).</p>
  
  <p>This is in the controller</p>
  
  <pre><code> $termino = $_POST['search']);
   $locale = LaravelLocalization::getCurrentLocale(); //es in this case
   $products = Product::where('title', 'LIKE', "%\"{$locale}\":%{$termino}%");
  </code></pre>
  
  <p>This is the content of the field 'title' in the database.</p>
  
  <pre><code>{"es":"PAN DE LE\u00d1A"}
  </code></pre>
  
  <p>The search returns 0 results.</p>
  
  <p>I am sure the problem is the codification and I don´t know how to resolve it.</p>
  
  <p>The codification is utf8mb4.</p>
  
  <p>Thanks</p>
