Do multiline tweet!

[ghjardim]

Hi! I'm trying to post a multiline tweet using:

#$msg = string with \n
echo "$msg" | bti

But the result is a tweet with just the first line. If message is "Hi!\nHow are you?", bti posts only "Hi!".
Is it a feature that bti lacks support of? Or already there's a way to post multiline tweets?
