How to Get Improper Characters to stop Displaying in ASP .NET/HTML Cod

I am new to web development, and i am receiving an issue with a piece of code that is written in ASP .NET/HTML. (The code that generates the portion of the page that is causing invalid characters to be displayed is shown below. The portion of the page that is rendering the invalid characters can be seen in the attached image.) Could someone explain what is causing the invalid characters to appear in in front of the copy right sign and after the Rights sign? Any help would be greatly appreciated.

    <div id="footerNavSeals">

        <script type="text/javascript" src="https://seal.verisign.com/getseal?host_name=www.somecompany.com&amp;size=S&amp;use_flash=NO&amp;use_transparent=NO&amp;lang=en"> </script>

        <a style="padding-right: 20px"></a>
        <br />
        <a href="http://www.verisign.com/ssl/ssl-information-center/" target="_blank" style="padding-right: 20px;
            padding-left: 5px; padding-bottom: 5px; margin: 0px; font: bold 7px verdana,sans-serif;
            color: #000000; padding-top: 5px; text-align: center; text-decoration: none">ABOUT

If your website is build using DOTNET, you could add <globalization> to web.config file as below:

<globalization
            requestEncoding="utf-8"
            responseEncoding="utf-8"  />

OR

maybe even add <%@CodePage=65001 %> on your ASPX page directives (but this would be required on all pages)

If using CLASSIC ASP please use code as provided:

<%@ Language="VBSCRIPT" CODEPAGE="65001"%>
<%      
    Option Explicit
    Response.CharSet = "UTF-8"
%>

Also, use &copy; for the copyright symbol.

In agreement to both above experts comments, I woudl like to add some points:

1. Could you make ensure that you have set doctype for the .aspx page properly like as: (2nd line after Page directive mostly)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

2. Is your browser character encoding set to default to Western (ISO-8859-1) (Mozilla Firefox). You can set it by Tools -- Options -- Content -- Advanced tab for fonts --  Default Character Encoding.

or try to set it to Unicode (UTF-8) either. Because those things override the page settings, if you have allowed browser settings to override.

3. The code you shared is having last <div> element extra. Sometimes improper closing of tags also causes problems. So make sure that there is no improper ending of any elements.
