Thank you for your patience. In this instance, we recommend the “directly over” approach to the question mark. We don’t believe a grade 1 indicator is needed for the question mark, as it is at the end of the sequence and would not be confused with an opening quotation mark.
Please note, also, that the check mark at the bottom of the page is brailled as dots 4, 146, officially adopted a few weeks ago. This replaces the proposed symbol of dots 5, 146.
