The quotation marks in your sketch are "smart quotes", the stylized quotes that Microsoft Office products replace normal quote marks with to make it "look better"; in other words, the sketch was copy'pasted into and out of microsoft word/outlook/etc, or from a website that did the same thing.
The smartquotes are unicode characters that are not valid an arduino sketch - only real quote marks are valid.
Solution is simple - delete each quotation mark and retype it.
