Alternative symbol sets for footnote marks

Question

The footmisc package describes 3 additional systems in which one can apply numbering to footnotes in a paper:

bringhurst: ∗, †, ‡, §, ||, ¶.

chicago: ∗, †, ‡, §, ||, #.

wiley: ∗, ∗∗, †, ‡, §, ¶, ||.

This is in addition to these methods:

arabic numerals: 1, 2, 3, 4, 5.

roman numerals: I, II, III, IV, V.

letters: a, b, c, d, e.

For my purposes, I think a system such as bringhurst, chicago, or wiley are suitable, because custom symbols are used:

• Arabic numerals appear to frequently throughout my document already.
• I can't find single-character unicode roman numerals exceeding 12. When rendered in XeTex, numbers above (such as "ⅫⅡ") appear with an added space.
• The letters in the alphabet look too much like the text of the document.

However, I find that the bringhurst, chicago, or wiley systems has some problems:

• They are limited to 6 or 7 symbols. I need at least 30, if not more.
• They do not appear to follow a logical pattern explaining the order or shape.
• They use symbols such as ¶, § and #, which I think usually carry very different meanings.

Are there any other sets of symbols within LaTeX's packages or from unicode which you think could make good footnote marks?

Answer 1

From the alphalph package documentation:

1.2.3 Multiple symbols

LATEX's standard set of footnote symbols contains doubled symbols at the higher positions. Could this principle be generalized? Yes, but first we need a clean footnote symbol list without doubled entries, example:

\usepackage{alphalph}
\makeatletter
\newcommand*{\fnsymbolsingle}[1]{%
  \ensuremath{%
    \ifcase#1%
    \or *%
    \or \dagger
    \or \ddagger
    \or \mathsection
    \or \mathparagraph
    \else
      \@ctrerr
    \fi
  }%
}
\makeatother
\newalphalph{\fnsymbolmult}[mult]{\fnsymbolsingle}{}
\renewcommand*{\thefootnote}{%
  \fnsymbolmult{\value{footnote}}%
}

The own definition of \fnsymbolsingle has the advantage that this list can easily modified. Otherwise you can use \@fnsymbol directly, because it uses the same first five symbols.

\usepackage{alphalph}
\makeatletter
\newalphalph{\fnsymbolmult}[mult]{\@fnsymbol}{5}
\makeatother
\renewcommand*{\thefootnote}{%
  \fnsymbolmult{\value{footnote}}%
}

Answer 2

As I outlined here, this is how you would go about making a custom footnote counter.

\makeatletter
\newcommand*{\wackyfn}[1]{%
  \expandafter\@wackyfn\csname c@#1\endcsname%
}

\newcommand*{\@wackyfn}[1]{%
  $\ifcase#1 \or1\or2\or3\or4\or5\or6%
    \else\@ctrerr\fi$%
}
\renewcommand\thefootnote{\wackyfn{footnote}}
\makeatother

This actually just makes a counter that goes up to 6 and then fails. But replace the numbers with whatever you want, and add more \or foo type things.

As for what symbols to use, there are packages like marvosym and pifont that contain a bunch of symbols.

Answer 3

You can use Greek numbers.

\documentclass[12pt]{article}
\usepackage{fixltx2e}
\usepackage[greek,english]{babel}
\begin{document}

\makeatletter
  \setcounter{footnote}{0}%
\def\@fnsymbol#1{%
     \greektext
     \TextOrMath {\greeknumeral{#1}}{\greeknumeral{#1}}
  }

\renewcommand\thefootnote{\@fnsymbol\c@footnote}%
 \def\@makefnmark{\rlap{\@textsuperscript{\normalfont\@thefnmark}}}%
 \long\def\@makefntext#1{\parindent 1em\noindent
 \hb@[email protected]{%
     \hss\@textsuperscript{\normalfont\@thefnmark}}#1}%

\latintext

First\footnote{One}, second\footnote{two}, third\footnote{three}, fourth\footnote{four},
 fifth\footnote{five}, sixth\footnote{6},seven\footnote{7},eight\footnote{8},nine\footnote{9}, ten\footnote{10}, eleven\footnote{11}
\end{document}

Run greek.dtx from babel to find a bit more details for greek numbers. Personally I wouldn't use them, neither would I use 30 footnotes on a page (critical edition or not), it would plainly be unreadable. I would rather use a combination of end notes and footnotes.

Answer 4

I completely agree with jon comment: having 30+ footnotes per page almost demands Arabic numerals (using 30+ other symbols could result really confusing); I don't think that Arabic numerals for the footnotes will conflict with other use of Arabic numerals in your document, but if you insist on changing them, you could slightly modify them (using italicized numerals, for example). The perpage, and maybe para, options from footmisc seem also mandatory, so you could say something like

\documentclass{article}
\usepackage[paperheight=2cm]{geometry}% just for the example
\usepackage[perpage,para]{footmisc}

\renewcommand\thefootnote{\itshape\arabic{footnote}}

\begin{document}

text\footnote{First footnote.} text\footnote{Second footnote.} text\footnote{Third footnote.}

\end{document}
