Oristar's WP program or browser or whatever probably automatically used an open-single-quote because there was a space in front of the '. The only reason mine doesn't look like that is that the open and close quotes look the same in this typeface...
The -- method is a typewriter convention... A "real" dash can be accessed in Windows programs by using Num Lock. Hold down the Alt key and type 0151 on the number keypad and Voila: ?- ! Lots of special characters can be accessed this way; Google ASCII for a list. (I much prefer ?-; I use -- here a lot because it's faster...)
p.s. Oristar, I'm a she

p.p.s. An en dash (yeah, the width of an N) is Alt0150. Technically, it should be used in phone numbers and hyphenated words, leaving only end-of-line breaks for the lowly hyphen... Or end-of-line breaks, I should say.
