title: change color of special characters in HTML
body: <p>I've a Unicode HTML page (saved in DB), is there anyway that I can programmatically change color of all "." and ":" characters in text (please pay attention that my HTML content has also inline CSS which may contain "." or ":" characters, but I just want to change color of the mentioned characters in real text.</p>
  
  <p>what are my options? One way can be finding these characters in the text and put them in  tag, so that  can be styled, any other suggestion? (if I'm going to use this method, how can I distinguish between HTML/CSS characters and real characters in the text?) I'm using ASP.NET/C#</p>
