Of course it does. It's exactly, what this function is for:
<http://www.php.net/manual/en/function.mysql-real-escape-string.php>
| mysql_real_escape_string() calls MySQL's library function
| mysql_real_escape_string, which prepends backslashes to the following
| characters: \x00, \n, \r, \, ', " and \x1a.

Yes, it has. Because PHP has this ability:
'\n' is a string, containing a backslash and an n
"\n" is a string, containing only a newline character
<?php
$db = mysql_connect('localhost', ..., ...);
$data = 'CÊ=3Fa=3F³Ýöâ8T\TBÆ';
var_dump(mysql_real_escape_string($data, $db));
$data = "Foo\nBar";
var_dump(mysql_real_escape_string($data, $db));
$data = 'Foo\nBar';
var_dump(mysql_real_escape_string($data, $db));
?>
