Can't add quotation marks in terminal

I am trying to complete lesson 7 but I can’t seem to be able to type quotation marks into the terminal. I can type the quotation marks in the editor with no problem but nothing shows up when I try in the terminal. Am I missing something here or is this a bug?

Have a look at this topic, I think that it will help:

Thanks for the reply but the link unfortunately did not help me. It did give me an idea of what to look for though and was able to finally solve the problem by changing my keyboard input to Unicode Hex on my mac. Hopefully this can be of help to someone.
