In your browser's address bar you can type this URL to see what the
character is:

javascript:alert(unescape('%3D'));

Or if you have firebug, console.log(unescape('%3D'));

In this case it's an = and is probably being encoded because it has
significance in the source. Maybe the last character of an email
message line can't be a space or an = so they get encoded to =20 and
=3D.
