I'm completing a problem set, one problem for which I literally have no idea what to do on. The graders would prefer to have a physical copy of the problem so I thought it best to include the
¯\_(ツ)_/¯ emoji as my answer, instead of something like "Dunno" or "No idea."
Option #1 is to include an image.
Beyond that I actually don't understand how this emoji works. The middle character is Japanese kana "tsu" and proves problematic - TeX wants it in math mode then renders "?" when it is.
