iphone - Windows notepad not supporting newline character ' '

Question

From my iPhone application I'm outputting data from text to a file. When opened with windows notepad, the data is all on one line and where there should be a new line a block character is present (showing that it's an unrecognized character or something). When opened with windows wordpad, it displays just fine.
Would there be something wrong in my code? I'm simply output ' ' when i want a new line.

NOTE : It's working fine with other editors like textedit, MS Word on mac as well as on windows.

Answer 1

Windows default is to use as end-of-line marker. Notepad only recognises that, other text editors may know about other line-end styles and render correctly.

EDIT
As VonC answers Notepad had an update (in 2018) where it now can recognize non-Windows end-of-line sequences.
