This problem is most likely caused by the book and not the font. My guess is that the book designer inserted an invisible control character between the quotation marks and the text. For example, a thin space.
If you're really curious, add the book to Calibre, open it with the Calibre Editor, search for the sentence and position the cursor after the opening quotation mark. You should see LEFT DOUBLE QUOTATION MARK in the lower right corner of the status bar. Then press the right arrow key and check the status bar; it should display the name of the character immediately following the quotation mark.
