You must use a literal line feed, e.g.:
LF='
'
(a single quoted newline) or, in a shell that supports this syntax:
LF=$'\012'
(note $ and single quote: double quotes here do not work)
to get the line-feed into the shell variable. You can also capture
the output of a program that emits the line-feed, but these are the direct
assignment methods.
For instance:
$ LF=$'\012'
$ echo "foo${LF}bar"
foo
bar
$
Lacking such capabilities, it's easy enough to use the printf shell
command to produce special characters as output (which you can
then capture, but various shells may also have Special Rules about
such captured output, so the direct assignment method is better, in
my opinion).
