missing accented characters lualatex in texlive2016

Question

If I process the following beamer class with lualatex (texlive 2016), the Á charactert is missing in the output pdf, but í appears correctly. This problem is not showing with laulatex of texlive 2015.

The following warning appears in the log file

{/home/zunbeltz/texlive/texlive2016/texmf-var/fonts/map/pdftex/updmap/pdftex.map } Missing character: There is no Á (U+00C1) in font cmr10!

The MWE is saves as utf-8 file:

\documentclass{article}

\begin{document}
\begin{itemize}
\item Ángel
\item Pedro Rodr\'{\i}guez
\end{itemize}
\end{document}

Add \usepackage{fontspec}. By the way, typing Rodr\'iguez has been possible for several years. — egreg, Jun 29 '16 at 08:56
@egreg: Shouldn't this be done automatically by beamer by detecting luatex? Do you think I should open a bug against beamer? — TeXtnik, Jun 29 '16 at 09:31
Where's beamer mentioned in your example? Anyway, I don't think you can blame beamer: if you use the class with LuaLaTeX you should know that some setting is needed. — egreg, Jun 29 '16 at 09:35
@egreg: Sorry, I first show the problem with beamer and later notice that it was also with article. Why was it working fine with tl2015 and not tl2016? (I guess is all the changes in luatex 0.95). From the fontspec manual: "The fontspec package allows users of either XeTeX or LuaTeX to load OpenType fonts in a LaTeX document." In this case we are using the standard fonts in LaTeX; so, shouldn't the LaTeX kernel do the job to typeset this fine without loading fontspec manually? — TeXtnik, Jun 29 '16 at 09:43
@JLDiaz: To show that the problem is with the "utf8" characters. — TeXtnik, Jun 29 '16 at 09:46
@egreg: I think I have to apologise! It is not working with TL2015! I think I was confused by several changes between TL2015 and TL2016. — TeXtnik, Jun 29 '16 at 09:51

If I compile the following example with LuaLaTeX from TeX Live 2015

\documentclass{beamer}

\begin{document}

\begin{frame}

\begin{itemize}
\item \'Angel
\item Ángel
\item Pedro Rodr\'{\i}guez
\item Pedro Rodríguez
\end{itemize}

\end{frame}

\end{document}

I get

which is expected.

If I add also \usepackage[T1]{fontenc}, the output is

but it is pure luck (see fontenc vs inputenc for an explanation).

Always load fontspec when compiling with XeLaTeX or LuaLaTeX

\documentclass{beamer}
\usepackage{fontspec}
\begin{document}

\begin{frame}

\begin{itemize}
\item \'Angel
\item Ángel
\item Pedro Rodr\'{\i}guez
\item Pedro Rodríguez
\end{itemize}

\end{frame}

\end{document}
