Namur: I had seen those weird characters on quotes once or twice but had no idea what was causing it.
Thanks.
Hmm, my post is now updated - if that string of characters is included as-is into a post, it'll simply be removed (which I didn't notice until I read your reply).
Of course, that shouldn't be much of a problem as it's quite unlikely that someone types it (either deliberately or by chance), save for a thread like this one.
EDIT: hmm, wonder if this works.

EDIT2: Right, the text was removed, making the quote empty, breaking it. (I tried "quoting" the character string from the broken quote).
