An interesting thought —
If I cut and paste, and get the screwy looking characters, then my post is not an exact copy of the source.
And maybe not a copyright problem?
Probably a false hope. In reality, when the evil forces are after you/us (Drudge interview reference), who cares about the details.
Pray hard. Be ready.
Love and Peace —
I deal with this in my work all the time...MS Word is notorious for adding weird character code that translates into special characters on the web. So I always tell my people to just quickly paste it into Notepad first before copying it. It's faster than having to go through the text and swap out every curly quote or apostrophe.
