Weird Notepad Behavior

I found this post concerning a weird behavior of notepad when typing some particular texts. Here's how,

1. Open up Notepad
2. Type in this sentence exactly (without quotes): "this app can break"
3. Save the file to your hard drive.
4. Close Notepad
5. Open the saved file by double clicking it.

Weird huh! This is also posted here, with some explanation.
