Non-latin characters incorrectly encoded

There are some strange encodings inside function _freelinking_do_filtering().
I don't know what for they are, but it seams that the extra character encoding breaks text when used later for "wikitools".

Quick-and-easy fix below.

Change:

      if (preg_match('/^(http|mailto|https|ftp):/', $freelink)) {
         $replacement = '<a class="freelinking external" href="' . $freelink . '">' . $phrase . '</a>';
      }
      else {
        $replacement = l($phrase, 'freelinking/' . rawurlencode($freelink), array('class' => 'freelinking'));

      }

to:

      if (preg_match('/^(http|mailto|https|ftp):/', $freelink)) {
         $replacement = l($phrase, $freelink, array('class' => 'freelinking external'));
      }
      else {
        $replacement = l($phrase, 'freelinking/'.$freelink, array('class' => 'freelinking'));
      }

and also:

    else if ($allowcamelcase) { // it's a CamelCase, expressions are a bit simpler
      $pattern = '/\b' . $wikiword . '\b(?![^<]*>)/';
      $phrase = $wikiword; // consistency for the db
      $freelink = $wikiword; // also for the db
      $replacement = l($wikiword, 'freelinking/' . urlencode($wikiword));
    }

to:

    else if ($allowcamelcase) { // it's a CamelCase, expressions are a bit simpler
      $pattern = '/\b' . $wikiword . '\b(?![^<]*>)/';
      $phrase = $wikiword; // consistency for the db
      $freelink = $wikiword; // also for the db
      $replacement = l($wikiword, 'freelinking/' . $wikiword, array('class' => 'freelinking'));
    }
