Charset mismatch exacerbated by uninformed use of Fancy Quotemarks. It sneaks in when you round-trip documents between Macintosh MS Word, Windows MS Word, the Web, and back again. And it wouldn't be a problem if people would just write all their programs to use UTF-8.

I've had a hate-on for the Òs for like 8 years. Users shouldn't have to be experts just to see other people's stupid quotemarks.
