HTML entities in iCal export

When you are including specials characters in an event description like : ", ', à, é... they are translate to HTML entities in the iCal.

For exemple go to:
http://drupal.demo.civicrm.org/civicrm/event/manage/settings?action=update&reset=1&id=1
Change the description with some specials characters, why not some french "Un jour à Paris"
Then check out the description here:
http://drupal.demo.civicrm.org/civicrm/event/ical?reset=1&list=1
The description is now: "Un jour &agrave\; Paris"

And BTW, why is there a \ before the semi-colon?

Until an official fix, here is mine:
File : administrator/components/com_civicrm/civicrm/CRM/Event/BAO/Event.php
After line 795 add:
$info['description'] = preg_replace('/\\\\;/', ";", $info['description']);
$info['description'] = html_entity_decode($info['description'], ENT_QUOTES | ENT_HTML401, 'UTF-8');

I know it is not perfect, but still, it work, except for the double quote, I am still looking for a better solution.
