functions.php

function add_nonbreaking_space_to_text($title, $id = null){
  $title = explode(' ', $title);
  $length = count($title);
  if( $length >0){
    $title[ $length-2 ] .= " " . $title[ $length-1 ];
    array_pop($title);
  }
  return implode(" ", $title);

// Hook the function to the title
add_filter('the_title', 'add_nonbreaking_space_to_text', 10, 2);
