I am extremely reluctant to change anything from any of the works I do unless I absolutely have to. Anything else leads us down the slippery slope to adding memes into our dialogue, making characters swear for no reason, or just generally changing the story. Considering you recognized these as quotation marks, I'm suspecting I didn't absolutely have to.
Besides, isn't it more fun to read something closer to the original and learn a little something along the way?
