I'm writing this question because one little invisible problem has taken from me hours and hours of dummy searchings, and the time just has been wasted (here is that question: CSS: Is there any difference between these two parts?)
Does anybody know how the character 0x08 ("backspace" in ASCII) can be written into a text using a MacBook and a simple IDE (I use the "Coda")?
There is no ability to press Alt + 08 on MacBook (there is no digital keys part on the MacBook's keyboard).
How it can happen?
Not sure if this is the easiest way, but:
Since the character is non-printable, it doesn't actually show anything in the text editor, but (at least in TextEdit) you will see that you have to hit the left or right arrow key more than once to move past it. I also confirmed by dumping the file in hex that it contains a 08 byte.
You could also use this technique to set up a Text Substitution in the Text tab of the Language & Text system preference panel.
Shift + Up Arrow + Delete/Backspace. It's a bug.

Did you copy & paste it from anywhere? Because the only way I know - apart from what SCFrench suggested - is to enable this in Terminal by typing:
stty erase
SPACE CTRL+V CTRL+H RETURN
