title: Weird characters though using the right encoding
body: <p>I work on a website that has different language interfaces, so far I use english and german.</p>
  
  <p>when the german text is loaded, it shows weird characters like the following screenshot</p>
  
  <p><img src="https://i.stack.imgur.com/SpgGx.png" alt="enter image description here"></p>
  
  <p>though I use</p>
  
  <pre><code>header('Content-type: text/html; charset=utf-8');
  </code></pre>
  
  <p>and also in the html header</p>
  
  <pre><code>&lt;META http-equiv="content-type" content="text/html; charset=utf-8"&gt;
  </code></pre>
  
  <p>what else can I do to solve it ?</p>
  
  <p>Thanks</p>
