Ok. I have a replicable oddity here. I’m copying text from site into DTP. Any character that is contiguous to a quotation mark—single or double—is elided upon pasting as a ⌘N “new with clipboard” along with said quote mark. Très bizare, non? In the case of the word final single quote (i.e. apostrophe), the quote and the two following characters disappear.
