HEXADECIMAL VALUE 0X03 is an invalid character
<p>This is the source of a web page</p>

<pre><code>&lt;html lang="pl"&gt;
&lt;head&gt;
&lt;meta http-equiv="content-type" content="text/html;charset=utf-8" /&gt;
&lt;/head&gt;

&lt;body&gt;
&lt;p&gt;Da&amp;#32;brow&amp;#35;a G�rn&amp;#x3;icza&lt;p&gt;

&lt;/body&gt;

&lt;/html&gt;
</code></pre>

<p>I need to browse this page and copy the text shown </p>

<p><a href="https://i.stack.imgur.com/uNKs5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uNKs5.png" alt="the text to be copied"></a></p>

<p>After that, I have pasted this text into an input text box of an asp.net mvc application in order to create a new record into the database. 
The meta charset of the layout page is "utf-8"</p>

<p>If I go to Visual Studio 2013 in debug, when the create action of the controller is executed, I can see the following string </p>

<p><a href="https://i.stack.imgur.com/uXJZB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uXJZB.png" alt="this is the address in debug mode"></a></p>

<p>This address has stored into a column of type nvarchar(255), and from sql management tool I see the same text as seen before:</p>

<p><a href="https://i.stack.imgur.com/77mge.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/77mge.png" alt="this is the address from the database"></a></p>

<p>If I copy and paste the address from database column to notepad++ I can see
<a href="https://i.stack.imgur.com/VDDHU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/VDDHU.png" alt="enter image description here"></a></p>

<p>After that I have to call a svc service in order to send the address data but I am receiving from the other side this exception</p>

<blockquote>
  <p>ERROR TRANSFORMING XML '' HEXADECIMAL VALUE 0X03 is an invalid
  character.</p>
</blockquote>

<p>How can I avoid this exception being thrown ?</p>
