Simple; the man pages are processed by nroff, which uses these for
underlining, boldface, and the uparrow character, as you guessed.
Other combinations include
	o^H+  for a bullet,
	s^HS  for a section symbol,
	etc.

nroff, you see, tries to do its best to be able to be used with troff
input, so that 1) you can use it for draft copies of your troff
document, and 2) if you don't have any high-quality output device, you
can still nroff and read someone else's troff document.

more takes the _^Hc and uses underline (if available) or standout mode
to display the character(s)!
