Columns are restricted to ASCII only, though. So when you paste that text into a column (or a questioner does it), the non-ASCII character gets all messed up.
If it's your own text that has that problem, you can either turn off the smart-quote feature in your word processor, or go back AFTER you've pasted the text into your column and manually replace every smart quote with a regular quote from the keyboard.
Unfortunately you can't edit the questions in your column unless you asked them yourself, so there isn't anything you can do about that. Sorry!
