title: Can't decode UTF8 for turkish letters
body: <p>I am trying to fetch rows from a SQL-Table with the <code>utf8_unicode_ci</code> collation.
  I tried generating a conversion with <a href="http://www.hardcodet.net/2010/03/silverlight-text-encoding-class-generator" rel="nofollow">this tool</a>, but it didn't really help.</p>
  
  <p>In the table the cell contains:</p>
  
  <pre><code>Hocam ” You can go out ” ne demek ?
  + Dışarı çıkabilirsin.
  - Teşekkürler
  </code></pre>
  
  <p>and decoded using the tool (with encoding code windows-1254/iso 88599) it's:</p>
  
  <pre><code>Hocam ” You can go out ” ne demek ?
  + D??ar? ç?kabilirsin.
  - Te?ekkürler
  </code></pre>
  
  <p>I am setting the encoding like this</p>
  
  <pre><code>WebClient wc = new WebClient();
  //wc.Encoding = Encoding.GetEncoding("ISO-8859-1");
  wc.Encoding = new CustomEncoding();
  </code></pre>
