As for an example of the usage of the function unicode_encode:

<?php
  header ('Content-Type: text/plain; charset=ISO-8859-2');
  $encoded = unicode_encode ('\u0150\u0179', 'ISO-8859-2');
  echo 'Unicode semantics: ', ini_get ('unicode_semantics'), PHP_EOL, 'The string itself: ';
  printf ($encoded . PHP_EOL, '%s');
  echo 'The length of the string: ', strlen ($encoded);
?>

The above example will output (please note that there will be characters instead of entities in the output):

Unicode semantics: 1
The string itself: &#336;&#377;
The length of the string: 2
