Punctuation marks and footnotes have disappeared

My document has long been in process. Therefore, it has seen an upgrade from Windows v1.9 to v3 Beta, and innumerable Beta updates. It has been a while since I have worked on this book. Now that I have begun again in earnest, my document in the latest Windows Beta ( has:

— replaced quotation marks, apostrophes, hyphens, bullet points, and other punctuation - with the exception of periods and commas - with black question mark icons
— made all the footnotes disappear

I have tried numerous font changes to no avail.

Has anyone experienced this issue, and is there a way restore the punctuation and footnotes?

a) this should be in the Beta Testing forum;

b) information about your version of Windows, set up, and language used would give people the chance to help you.


A belated thanks, Mark. I will do so.
