Added "®" to transliterations

One of my websites which uses the oEmbed-extension to include videos suddenly started to throw an error for every page that contained a video with an "®" in the title. I debugged my xml and noticed that there seemed to be a problem with the handle-transformation of this character:

    <title handle="intel�-leap-ahead™-|-music-and-theme">Intel®: Leap ahead™ | Music and Theme</title>

Adding the "®"-character to translations.php solved the problem.
