But, but, but :: splutter :: a pipe and a dash are utterly different things.
Agreed in "normal English" and "strict usage", but in "search engine algorithmic understanding of intended meaning" (which must be flexible to attempt and accurately determine what those not well versed in the strict use of characters are trying to say) they really have to be treated as "not much different", because they are each often misused.
And, technically, the correct separator rather than - would be – or — not a -, since a - in the source code could be a hyphen or minus sign, but as far as algorithmic understanding of an intended page title (and likely onpage text) goes, they basically all have to be seen as separators without much impactful difference in actual rankings.
