For many, this is its major advantage—by having virtually no features, it cannot go wrong—but especially for software developers, it has often proven an annoyance. >That's because Notepad has traditionally only understood Windows line endings. Windows, Unix, and "classic" MacOS all use different conventions for indicating the end of a line of text. Windows does things correctly: it uses a pair of characters, the carriage return (CR) followed by the line feed (LF). Two characters are needed because they do different things: the CR moves the print head to the start of a line; the LF advances the paper by one line. Separating these is valuable, as it allows for effects such as underlining to be emulated: first print the text to be underlined, then issue a CR, and then print underscore characters.
