notepad, the plain text editor that comes with windows, has a silly bug. do this:
- Open up Notepad
- Type in this sentence exactly (without quotes): "this app can break"
- Save the file to your hard drive in ANSI encoding.
- Close Notepad
- Open the saved file by double clicking it.
instead of what you wrote, you will see squares, or chinese/japanese/korean gliphs, if you have them installed.
