The LaTeX text footnote symbol sequence begins with ∗ † ‡ § ¶ ∥
. I'd like to define a vertical double asterisk ⁑
(\textastdbl
) so that I can insert it into the sequence: * ⁑ † ‡ § ¶ ∥
(note: actual amendment of the footnote symbol sequence isn't part of what I'm asking for).
Here is some code that approximates how things should look like:
\documentclass{article}
\newcommand*{\textastdbl}{*\llap{\raisebox{-1.35ex}{*}}}
\newcommand*{\textastdbltight}{\raisebox{-0.1ex}{*}\llap{\raisebox{-1.25ex}{*}}}
\begin{document}
A new footnote symbol sequence with a vertical double asterisk:
*\textastdbl(\textastdbltight)\dag\ddag\S\P\textbardbl
\end{document}
My symmetry requirement is that the middle of the symbols \textastdbl
and \ddag
should be at the same height. I think that \textastdbl
is too wide, so something like \textastdbltight
in my code has about the right look, except the ex
-values weren't chosen precisely and should instead be calculated from the vertical dimensions of the *
and \ddag
symbols. The resulting symbol should be an ordinary text mode symbol. If *
weren't top-down symmetric, an additional challenge would be to flip it for the bottom half.
Update: For those using such a symbol, the Unicode codepoint is U+2051
. Load package accsupp
and enclose the macro definition in \BeginAccSupp{method=hex,unicode,ActualText=2051}
[...]\EndAccSupp{}
to produce the right codepoint upon pasting.

it doesn't look bad as it is. – David Carlisle Jun 27 '13 at 12:06
