title: Convert special character (i.e. Umlaut) to most likely representation in ascii
body: <p>i am looking for a method or maybe a conversion table that knows how to convert Umlauts and special characters to their most likely representation in ascii.</p>
  
  <p>Example:</p>
  
  <pre><code>Ärger = aerger
  Bôhme = bohme
  Søren = soeren
  pjérà = pjera
  </code></pre>
  
  <p>Anyone any idea?</p>
  
  <p><strong>Update</strong>:
  Apart from the good accepted Answer, i also found PECLs <a href="http://www.php.net/manual/en/normalizer.normalize.php" rel="nofollow noreferrer">Normalizer</a> to be quite interesting, though i can not use it due to the server not having it and not being changed for me.</p>
  
  <p>Also do check out <a href="https://stackoverflow.com/questions/3542717/how-to-transliterate-accented-characters-into-plain-ascii-characters">this Question</a> if the Answers here do not help you enough.</p>
