title: HTML form - input validation with Alphanumeric with symbols ()._-‘ only
body: <p>I want to validate below input with <strong>Alphanumeric</strong> and <strong>()._-‘</strong> symbol only. </p>
  
  <p><code>&lt;input type="text" name="companyName" value="" pattern="[A-Za-z0-9()._-‘]+" title="Alphanumeric with symbols ()._-‘ only" required&gt; &lt;/p&gt;</code></p>
  
  <p>But, when I try the input, only <strong>._‘</strong> can be used, <strong>()-</strong> are not working.</p>
