I have got TeXlive 2016 on Windows 64 bit. When compiling the attached tex file with pdflatex, surprisingly the dash in the footnote disappears.

\documentclass[english,10pt]{beamer}

\begin{document}
	\begin{frame}{abc}{abc}
		a\footnote{2971–2987}
	\end{frame}
\end{document}

Not a beamer bug: pdfTeX can't handle the UTF-8 char here unless you do

\usepackage[utf8]{inputenc}
