According to Collins, in American English Dewey can be pronounced either /ˈdui/ or /ˈdjui/ (only surnames are listed there as examples, though). How are the triplet cartoon characters Huey, Dewey and Louie commonly pronounced, with /ˈdjui/, /ˈdui/ or both?
(EDIT: Since there have been efforts to canonize the Duck Universe in the past, I had not ruled out that some sort of clarification was given at some point of time, as a recommendation or even as some kind of "it's spoken like xxx, guys!" (even if the latter would sound a bit arrogant). I couldn't find anything on the Web about the prevalent pronunciation.)
