So I guess it could be years, or they may never fix the bug that Word cannot execute a "find and replace" for punctuation (commas, semicolons, quote marks etc) of a certain font type and size and change it to another? And if they ever do, will they let me know?

I did write up a report about it here:

Word 2019 cannot search punctuation in Nirmal or Mangal fonts and convert to Times New Roman – Welcome to Word's Suggestion Box!
