For the translation issue it would be solved if using the translation function for printing the description.
For the special chars issue maybe incoding and decoding it with htmlentities().
Maybe I can change this in the core but what about future updates ?
Speaking update, I can I know there is an available update, does it create an message in the admin section ?
Does the link I got the first time will be a link that goes to the updated plugin download ?
Thank you.
