This is a result of WordPress's "texturize" function, which is buried deep within the main core of WP. It changes all the 'normal' punctuation marks with their 'prettier' alternatives, and it has always driven me insane.
Funny story: I had the good fortune to drive Matt Mullenweg to dinner after a WordCamp, and in the car we talked about many things. We got to the topic of typography, which made me lament the fact that I was always frustrated when all these blogs would replace straight quotes with curly quotes and how hard it was to copy/paste them elsewhere. "Oh, yeah," he said. "I wrote that."
At that point I completely forgot who I was escorting, shot Matt a sideways glare and said, "YOOOUUUUUU!!!!!!!"
I was immediately embarrassed, but he took it in stride :)
I can't find the interview, but I think this was actually one of the things that prompted Matt into creating Wordpress (the inability of existing solutions to do decent typography).
