title: iconv - Notice: iconv() [function.iconv]: Detected an illegal character in input string
body: <p><code>print iconv('UTF-8', 'us-ascii//TRANSLIT', 'Ин Совет Россия, дог фес ю!');</code></p>
  
  <p>I don't get it why it throws this notice. The string is a valid UTF8.</p>
  
  <p>It should convert all characters to their ASCII equivalents, right?</p>
  
  <p>For example <code>И</code> should be <code>I</code>, <code>н</code> should be <code>n</code> and so on...</p>
