¿

When I was in college I came up with my own system of taking notes, as most people do.

Whenever I had a question I used the Spanish ¿ at the beginning of the question so it stood out to me on the page. Alt+168 on a keyboard by the way.

Yesterday at work I was sending an email an I considered using it. I didn’t.

My question is - would that be offensive?
It’s not only that I’m still in my probationary period at a new position but I just don’t want to be a jerk.

Anyone’s opinions on this are welcome.
