title: Some speciual caraters are translated to '?' in mysql database
body: <p>In my Android app, user types in some text that is then sent to a database (by using a URL with php). 
  All is working fine, except that only some of the special caracters are saved in the relevant field.</p>
  
  <p>For example, user has put in</p>
  
  <p>čćáæíœ</p>
  
  <p>and in the database I find the following: </p>
  
  <p>??áæí?</p>
  
  <p>The first 2 caracters and the last one have been translated to '?'</p>
  
  <p>The field is utf8_general_ci. The fact that some caracters work and others not, leaves me clueless. </p>
