From http://www.php.net/manual/en/function.chr.php#55978:

"I spent hours looking for a function which would take a numeric HTML entity value and output the appropriate UTF-8 bytes.  
I found this at another site and only had to modify it slightly; so I don't take credit for this."

<?php function unichr($dec) { 
  if ($dec < 128) { 
    $utf = chr($dec); 
  } else if ($dec < 2048) { 
    $utf = chr(192 + (($dec - ($dec % 64)) / 64));
