As of 1.8.6 more entities are shown wrong in the search results. So I digged around in the code and came across the following question:

Why do you use the custom $spec array instead of just reversing the function of htmlentities?

e.g. replace your existing code in robot_functions.php:

// first case-sensitive and then case-insensitive
//tries to replace htmlentities by ascii equivalent

foreach ($spec as $entity => $char) {
      $text = ereg_replace ($entity."[;]?",$char,$text);
      $title = ereg_replace ($entity."[;]?",$char,$title);
}
//tries to replace htmlentities by ascii equivalent
foreach ($spec as $entity => $char) {
      $text = eregi_replace ($entity."[;]?",$char,$text);
      $title = eregi_replace ($entity."[;]?",$char,$title);
}

With this:

$trans = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES);
$trans = array_flip($trans);
$text = strtr($text, $trans);
$title = strtr($title, $trans);

Using PHP4.3 and later, you could even make use of the new html_entity_decode() function.
