The problem came up in a braille guide word for an index. In print, it was "conflict--connotation", so the 'con' contraction from the second word follows a dash. In the Instructional Manual for Braille Transcribing, Section 7.5c, I see that the 'con' contraction cannot follow a dash, though it can follow other punctuation. I mentioned this to the proofreader, who told me there was no conflict using the dash next to the 'con' contraction. Hence my confusion.
