title: How to encode the plus (+) symbol in a URL
body: <p>The URL link below will open a new Google mail window.  The problem I have is that Google replaces all the plus (+) signs in the email body with blank space.  It looks like it only happens with the <code>+</code> sign.  How can I remedy this?  (I am working on a ASP.NET web page.)</p>
  <p><a href="https://mail.google.com/mail?view=cm&amp;tf=0&amp;to=someemail@somedomain.com&amp;su=some" rel="noreferrer">https://mail.google.com/mail?view=cm&amp;tf=0&amp;to=someemail@somedomain.com&amp;su=some</a> subject&amp;body=Hi there+Hello there</p>
  <p>(In the body email, &quot;Hi there+Hello there&quot; will show up as &quot;Hi there Hello there&quot;)</p>
