How do I create a new line using javascript that shows correctly in notepad?

I have a script that copies table cells from the browser into the user's clipboard. I loop through each cell and when a new line is needed I use

text += "\n";

If I paste the text into excel, it formats correctly and fills in the proper rows, however if I paste into notepad, it shows a symbol instead of creating a new line:

123□456□789

instead of:

123

456

789

Is there something else I can use that notepad will recognize as a line break?
