[Tex/LaTex] Different styles of footnote numbering with beamer

beamerfootnotesnumbering

I am writing a presentation in beamer and I use footnotes for references, making use of the \footnotemark and \footnotetext commands. When I use these in block, the numberings of marks and texts is different. I mean the marks are numbered using Arabic numerals (1,2,…) but the texts are numbered using small letters (a,b,…). Here is an image to illustrate this issue:

The corresponding source is

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usetheme{Frankfurt}
\begin{document}
  \begin{frame}{Sample frame}
    \begin{block}{Sample block}
      Some text\footnotemark[1]
      \footnotetext[1]{Footnote}
    \end{block}
  \end{frame}
\end{document}

Is there a way to solve this inconsistency and unify both numberings?

Best Answer

Use the regular \footnote mechanism. If you want to have the footnote at the bottom of the frame then you can include [frame] option. Note that beamer overwrites almost all the footnote mechanisms from scratch. Hence better not expect consistent behavior with other packages.

In fact omit footnotes if possible. 

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usetheme{Frankfurt}
\begin{document}
  \begin{frame}{Sample frame}
    \begin{block}{Sample block}
      Some text\footnote{Footnote}. Some other text\footnote[frame]{Another footnote}
    \end{block}
  \end{frame}
\end{document}
