title: Get emoticon's (chars) unicode code
body: <p>I need to get emoticon's code in format like 1F600 or 128512. It's just a symbol in my string now.</p>
  
  <p>I found that emoticons described in Uniicode encoding, but CharUnicodeInfo.GetNumericValue seems not working.</p>
  
  <p>How can i do this?</p>
  
  <p>Ok</p>
  
  <pre><code>var q = CharUnicodeInfo.GetNumericValue(text[0]);
  </code></pre>
  
  <p>where text[0] holds emoticon (in debug view it's just a picture)
  returns -1</p>
