As a sidenote, that character is the "general currency symbol".
It was intended as a place-holder in a font for a local currency
symbol (iso-8859-1 has, I believe, only yen, pounds, dollars,
and cents). But since iso-8859-1 is meant as an international
character set, which is _not_ supposed to be changed according
to locality, the inclusion probably was a mistake.

Though perhaps it has some usefulness as a doodad.

[ Your F1/F2 really shouldn't be inserting these things - they
  should be generating the appropriate key syms for F1, F2, etc ]

Hopefully, not by hitting F1/F2. Unless you specifically hook
to those key symbols.
