I noticed that when quote marks are converted to smart quotes in titles, the opening quote points the wrong way if it is preceded by an open parenthesis. See the title to this question.

Edit: Thanks for checking on different browsers, but it's not a browser issue. Just look at the HTML that is served:
Smart quotes in parentheses point the wrong way (”example”)
The one on the left should be “
Edit 2: looks like [
and {
are also triggering the wrong type of quote.
