no double space returns with nl2br()

[brakemach1ne]

To any who may be able to help,
I normally use $text = nl2br($text);
on text pulled from the database so that it will start a new line when it reaches the margin of the container that holds it. I use this function because it also keeps any "returns" that the user has placed in the text box. Unfortuanately, I've noticed that on a Macintosh, if the text reaches the margin, it looks as though it creates a "double space" return for the next line instead of a single space as it should. Any advice would come as more than a blessing.
peace,

Windows, Mac and UNIX all have different ways of doing LF/CR:

Windows = \r\n
Mac = \r
UNIX = \n

I always convert everything to the UNIX standard before sticking in the database:

$text = str_replace("\r\n", "\n", $text);
$text = str_replace("\r", "\n", $text);
