title: Convert Special characters into Html Encoded characters
body: <p>I want to converter all special characters into Html encoded characters.
  I found many post related to used <code>HttpUtility.HtmlEncode();</code> ,
  but it's only convert some of special characters like <code>"&amp;", "&lt;", "&gt;"</code>.</p>
  
  <p>Is there any way to convert all special character like <code>"š","Ø","þ","›","Ù"</code> into Html entity using C# or javascript?</p>
