Special Characters

Q. How do I insert an ellipsis in my manuscript? My computer keyboard can do that with a couple of keystrokes. Is this acceptable? Or should I type period + space for all three dots? Should these spaces be nonbreaking spaces?

Q. Can you tell me the CMOS preferred style for printed quotation marks: typographer’s marks or the default straight-line marks?

Q. We’ve been having a discussion in the office about whether to continue using diacritical marks on words such as decor and applique. The arguments turn on whether we consider them to be proper English words instead of imports, due to their familiarity to English speakers and the length of time that they’ve been part of the language. We couldn’t find a place where the editors addressed this issue in CMOS. Could you give us an opinion, please?
