title: Mysql UTF8 Encoding Issue - "Incorrect string value"
body: <p>I'm using Mysql (5.5.27) with .Net connector (6.5.4), and when i'm trying to insert some data, i'm getting following error.</p>
  
  <pre><code>Incorrect string value: '\xF3\xB6\xA5\x89f'...' for column 'STACK_TRACE' at row 1
  </code></pre>
  
  <p>I have already searched enough on stack overflow, and tried following charset &amp; collation for database, table and column.</p>
  
  <ul>
  <li>'utf8' 'utf8_general_ci'</li>
  <li>'utf8' 'utf8_unicode_ci'</li>
  <li>'utf8mb4' 'utf8mb4_general_ci'</li>
  <li>'utf8mb4' 'utf8mb4_unicode_ci'</li>
  </ul>
  
  <p>I have set 'charset=utf8' in connection string properly.</p>
  
  <ul>
  <li>Is there any thing wrong with that particular unicode character ?  I don't have control over the data, its collected from lot of android phones.</li>
  <li>Is it mysql bug ?</li>
  </ul>
