A couple of hopefully helpful hints: Once you've gotten the character into
one cell, you can then copy it to the clipboard to paste in other places if
you need to do this a lot.

While the method that Gord (and Bernard) would be the preferred one, you can
get a pretty good simulation of the symbol by underlining the + symbol:
while typing, just before entering the + key, hit [Ctrl]+[u] to begin
underlining, type the + and then [Ctrl]+[u] again to turn off underlining.
Of course this is pretty much useless if the entire text in the cell is to be
underlined. But there's little or no ambiguity if you use [ALT][0][1][7][7]
(from the number pad <g).
