You can open the keyboard exerciser from the world menu (by red-clicking anywhere on the grey background) > objects > demo. Just place it anywhere in the world, hover it, and press a key the displaying the unfiltered keyboard events. You can hover it and share us a screenshot of the resulting tooltip. For this particular issue, the preselected option (Test key stroke) should fit.

(Actually, a simpler way is to place a dollar ($) character right before the question mark, select both the dollar and the question mark, and press Cmd + I to inspect it to evaluate it as a literal character expression. The title of the opened window will tell us the ASCII code of that character. I suspect that this is NOT a 63, which would be a regular question mark, but a much larger number of a special character that the default fonts in the image cannot display.)
