That could be tough :) Literature shown to me was at school (many years
ago), and digging it up would be difficult. It's widely known that the
double-bar form does exist, though, at least!

I understand, although couldn't that same argument be used against many
of the characters in the 'Dingbats' section, such as the ornamental
variations of exclamation marks, quotation marks, and so forth? I do
realise these come from an existing character set, but there are indeed
still users of the double-bar form. Even my Concise Oxford Dictionary is
printed using the double-bar form (under the term, 'dollar').
I just thought it extremely odd that a character which is still in
common (albeit admittedly waning) use is not included in the set. Peter
Kirk made a valid observation with regards to the Lira symbol (U+20A4)
which Unicode admits often has U+00A3 (Pound sign) used in its place,
with the only difference being a double-bar on U+20A4.
