I have just spent 30 minutes searching for and adding wingdings to my syllabus.
My students, and their aesthetic pleasure, come first.
In the end, actually, I ended up using the tilda. Boring. Perhaps I can make it up to them by finding a stimulating font. And alternating between italics and boldface letters. Oh, how they will pay attention to the details thanks to these machinations. Late papers. What are they? Not accepted! (ha.)
