When I add an external image with a URL that contains an asterisk, it works in the image preview, but when I save, or do a page preview, it's a broken link. When I use the same URL as a link, the link is created, it's blue, it's underlined, but it's not clickable... If I replace the askterisk with %2a both cases work. (Links to Graphite graphs (http://graphite.wikidot.com/) often contain asterisks... so this is annoying.
