Make all footnotes numbered subsequently, but one with a symbol

Question

I was wandering if there's a way to make only one footnote appear with a symbol (*) instead of the number.

Thanks!!!

Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. — Speravir, Feb 06 '14 at 18:07
Please also have a look at Symbols instead of numbers as footnote markers – in the comments to Stefan’s answer, you’ll see how to change this for just one Footnote. — doncherry, Feb 06 '14 at 18:07
@Speravir I guess ... unless the OP wants exactly one footnote with one specific symbol, that might be far enough from both questions to justify a separate question, i.e. I would expect a good answer to be more than an amalgamate of the answers to these two questions. — doncherry, Feb 06 '14 at 18:11
@Speravir exactly, I need only one footnote to have a symbol. I have note 1-9 numbered, one "asterisked" note and then note 10 and so on — pierpaolo, Feb 06 '14 at 18:33
@pierpaolo Could you [edit] your question to describe this situation, with the example you just gave and optimally even with a minimal working example (MWE) with a few footnotes, each specifying what kind it should be? — doncherry, Feb 06 '14 at 18:38
Are you using hyperref or any packages that modifies the display/formatting of footnotes? — Werner, Feb 06 '14 at 18:46

If you're not using anything fancy in your document (like hyperref, say), you can redefine \@xfootnote:

enter image description here

\documentclass{article}
%\setlength{\textheight}{.3\textheight} Just for this example
\makeatletter
\def\@xfootnote[#1]{%
  \protected@xdef\@thefnmark{#1}%
  \@footnotemark\@footnotetext}
\makeatother
\begin{document}
This is a\footnote{Regular footnote} piece of text.
This is a\footnote[*]{Different footnote} piece of text.
This is a\footnote{Regular footnote} piece of text.
This is a\footnote{Regular footnote} piece of text.
This is a\footnote[$\dagger$]{Different footnote} piece of text.
This is a\footnote{Regular footnote} piece of text.
This is a\footnote[$\star$]{Different footnote} piece of text.
\end{document}

Wouldn’t it be semantically nicer to use \textdagger and something like \textasteriskcentered or one of bbding’s or pifont’s stars instead of the math mode versions? – doncherry Feb 06 '14 at 19:00
@doncherry: I followed the basic definition of \@fnsymbol in latex.ltx. – Werner Feb 06 '14 at 19:02
@Werner It seems to be working fine with hyperref on my end (with hyperfootnotes=true). Is there a particular reason to expect clashes? – triple_sec Feb 12 '20 at 07:28
@triple_sec: I know that hyperref changes/taps into a large number of document elements, so was concerned that it would influence that if redefining \@xfootnote. If it works, then go ahead; I probably didn't test it extensively. – Werner Feb 12 '20 at 17:04
@Werner I see—I do know what you’re talking about, hyperref can easily wreak havoc. I thought you had identified a specific clash, though. I didn’t check thoroughly, either, but, for what it’s worth, I identified no error message in the console and the output looked very nice. The custom symbols even had clickable hyperlinks attached to them! This is an elegant solution, thank you very much! – triple_sec Feb 13 '20 at 01:22
