Things You Can't Say in Notepad
If you're a Windows user, open Notepad and type in this phrase, without the quote marks and with no carriage return: "Bush hid the facts". Now save it and open it again.
The subversive text is probably gone, replaced by a line of white boxes, or Chinese characters if you have the font.
Weeeird.
It's not the massive right-wing conspiracy it might seem, though. The folks at WinCustomize.com discovered an odd bug in Notepad that's triggered by a text file consisting of a four-letter word, two three-letter words, and a five letter word. Some text does it -- "this app can break" is their example -- some doesn't.
