Oh no lol, the @#39 isn't my doing. That's an artifact of pasting "fancy" curled punctuation marks from Word or Google docs to the plain text format. (You'll have to talk to somebody else for the why of that, but it's just basically telling the browser to display a special character instead of the actual punctuation mark.)
