title: How to remove the first two characters of a QString
body: <p>How would I remove the the first two characters of a QString or if I have to put it a StackOverflows layman's terms:</p>
  
  <pre><code>QString str = "##Name" //output: ##Name
  </code></pre>
  
  <p>to </p>
  
  <pre><code>output: Name
  </code></pre>
  
  <p>So far I have used this small piece of code: </p>
  
  <pre><code>if(str.contains("##"))
  {
      str.replace("##","");
  }
  </code></pre>
  
  <p>..but it doesn't work as I would need to have <strong>"##"</strong> in some other strings, but not at the beginning. </p>
  
  <p>The first two characters may occur to be <strong>"%$"</strong> and <strong>"#@"</strong> as well and that mostly the reason why I need to delete the first two characters.</p>
  
  <p>Any ideas?</p>
