You forgot

char.init 0xFF
wchar.init 0xFFFF
dchar.init 0xFFFFFFFF

Shhh; don't tell anybody; I left those out of the quiz to weigh in favour of zero bit pattern init values. (This trick, i.e. omitting information, is one I learned from the Ministries of Statistics and (un)Employment.)

Seriously though, I imagine the D design choices to be influenced by the desire to propagate NaN and invalid UTF in their respective cases so as to detect uninitialized data errors. Hmm, guess one could argue the init issue for eons.

Well, I see this as a problem because I've often relied on default initialization being zero in my algorithms. I was bitten once when my algorithm worked perfectly with char but not with wchar. Turns out that char.init == 0 (contraty to what Andrei wrote) and wchar.init == 0xFFFF.
