# Mixing symbols and numbers as footnote markers

I have several numbered footnotes in a text, but some of them I would like to see them as symbols. I tried with the next command

\footnote[10]{this is a footnote}


and it works, it changes the next number by 10, but if intead of 10 I use \dag it doesnot work, or if I use \dagger it writes 8825. Any idea?

Thanks, probably the package bigfoot resolve the problem, but I was looking for something easier. Actually, hopefully, I found the next solution. If I define the next line in the preambule
\long\def\symbolfootnote[#1]#2{\begingroup%
