how to use tag in page title?

Does anybody have any insight into how to use a
tag or achieve a line break in a page’s title.
The primary reason that I’m trying to make this work is because I want the menu to show two words, one on top of the other; for each entry in the page menu on each page. Like a
in between each word.

I’ve found some older solutions here and there that no longer seem to be applicable.

Thanks for any help!
