What the !?K?

[potioncat]

I just replied to a post by Alla over at the main site. Her post looked 
fine. I copied it and did all my writing in word. Everything looked 
fine. Them I copied it all and pasted back in yahoo. Still looked good. 
I sent it. Now the part that was originally Alla's has all sorts of odd 
marks where punctuation is supposed to be. See post 182284 for full 
visual display.

I know this sort of thing has been brought up here before. At that time 
I actually went into the nether regions of my program and chose...and 
chose....whatever it was that you choose to keep you from getting ood 
marks.

I'm just wondering...what happened and how do I avoid it in the future?

Potioncat, who ought to bed, but isn't.
