When \n is used in the json of title, it displays a "LF" with a dashed border instead of starting a new line like in books.
Command:
/title @p title {"text":"this is a\nTITLE"}When this command is ran, what is in the attached picture happens.

You can't add a new line with title or subtitle. The strange character you see is just the character used to indicate a new line.
