title: get all Text Encoding in universal windows app
body: <p>I want to make windows application that convert text encoding of Txt file.
  so I need to get all text encoding supported by windows.
  I look for <code>Encoding.GetEncodings()</code> Method but it is not exist in Universal Windows Apps.
  so I try to get encoding by CodePage, and this is my code:</p>
  <pre><code>        List&lt;string&gt; list = new List&lt;string&gt;();
          List&lt;string&gt; errors = new List&lt;string&gt;();
          int[] code_page = { 0, 1200, 1201, 1252, 10003, 10008, 12000, 12001, 20127, 20936, 20949, 28591, 28598, 38598, 50220, 50221,
          50222, 50225, 50227, 51932, 51936, 51949, 52936, 57002, 57003, 57004, 57005, 57006, 57007, 57008, 57009, 57010, 57011, 65000, 65001 };
          for (int i = 0; i &lt; code_page.Length; i++)
          {
              try
              {
                  list.Add(Encoding.GetEncoding(code_page[i]).EncodingName);
              }
              catch (Exception ex) { errors.Add(code_page[i] + &quot;\t\t&quot; + ex.Message); }
          }
          }
  </code></pre>
  <p>And I have this result:</p>
  <h3>First list (Encoding)</h3>
  <ul>
  <li>Unicode (UTF-8)</li>
  <li>Unicode</li>
  <li>Unicode (Big-Endian)</li>
  <li>Unicode (UTF-32)</li>
  <li>Unicode (UTF-32 Big-Endian)</li>
  <li>US-ASCII</li>
  <li>Western European (ISO)</li>
  <li>Unicode (UTF-7)</li>
  <li>Unicode (UTF-8)</li>
  </ul>
  <h3>Errors list</h3>
  <ul>
  <li>37___No data is available for encoding 37. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.</li>
  <li>437__No data is available for encoding 437. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.</li>
  <li>500__No data is available for encoding 500. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.</li>
  <li>...etc</li>
  </ul>
  <p>and my question is there any way to get all windows text encoding.</p>
  <p>Thank you.</p>
