You can define your own $StrFoldFunction :

  $StrFoldFunction = 'FoldNZ';

  function FoldNZ($str) {
    $conversions = array(
      'â' => 'a',
      'ā' => 'a', # etc.
    );

    if(function_exists('utf8fold')) $str = utf8fold($str);
    else $str = strtolower($str);

    $str = str_replace(array_keys($conversions),array_values($conversions),$str);
    return $str;
  }

See as an example the function utf8fold() and the array $StringFolding in  
the file scripts/xlpage-utf-8.php.

Note that you should look into the text source of your wiki files. If you  
don't use UTF-8, chances are that your "ā" character is replaced by "ā"  
or "ā", or something else. If that's the case, use 'ā' => 'a', in  
your definitions.
