For those confused what an article about zombies (first link) has to do with questions marks in one's name, here's the relevant quote:

"Professor Robert Smith? (the question mark is part of his surname and not a typographical mistake)"

Coincidentally, I ran across Scott Shaw!'s homepage today: http://www.shawcartoons.com/bio.php

(...although there are plenty of other names with exclamation points, due to languages like Xhosa.)

And, of course, his name looks funny when someone is asking a question:

"Is that you Professor Robert Smith??"

And I wonder if he introduces himself as "Robert Smith Question Mark" ;-)

I wonder how you pronounce ?. Is it a click like Zulu or do you just have a rising intonation?

Rising intonation gets my vote. http://www.youtube.com/watch?v=JTbrIo1p-So (Tim? the Enchanter)
