That's odd, Wendy. I have two titles (that I can think of off the top of my head) that have had question marks in them for over a year. I know they didn't work when I first joined in 2010. I also have apostrophes in some, but commas and dashes don't work. Nor do accent marks. In fact, accent marks don't even work in keywords, which I would like because the foreign names of places, etc. are spelled wrong in my descriptions without the accent marks.
