带有撇号的 Bib 文件在编译期间会出现错误

我的文件中有以下 bib 条目：

@inproceedings {prekopa1980logarithmic,
title={Logarithmic concave measures and related topics},
  AUTHOR = {Pr\'{e}kopa, Andr\'{a}s},
  booktitle={Stochastic programming},
  year={1980},
  PUBLISHER = {Academic Press, London-New York}
}

我得到了未定义的控制序列错误

<argument> Pr\8
               0
l.383 \bibitem[Pr\80]{prekopa1980logarithmic}
                                             
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

我在 bib 文件中还有其他转义字符，但出于某种原因，这个特定条目有问题。如果我删除转义字符，问题就会消失。

如能提供任何关于如何解决此问题的提示，我们将不胜感激。

我的书目设置是

\bibliographystyle{alpha}
\bibliography{references}

我没有使用任何参考书目包，但我使用了我大学的论文模板，该模板附带了一些专有包。

我可以用

\begin{filecontents*}{\jobname.bib}
@inproceedings {prekopa1980logarithmic,
title={Logarithmic concave measures and related topics},
  AUTHOR = {Pr\'{e}kopa, Andr\'{a}s},
  booktitle={Stochastic programming},
  year={1980},
  PUBLISHER = {Academic Press, London-New York}
}
\end{filecontents*}

\documentclass{article}
\usepackage{hyperref}

\begin{document}

\cite{prekopa1980logarithmic}

\bibliographystyle{alpha}
\bibliography{\jobname}

\end{document}

再次运行后pdflatex，结果为bibtexpdflatex

! Undefined control sequence.
<argument> Pr\8
               0

问题在于作者姓名的输入方式：重音字母周围应该有额外的括号。

@inproceedings {prekopa1980logarithmic,
title={Logarithmic concave measures and related topics},
  AUTHOR = {Pr{\'{e}}kopa, Andr{\'{a}}s},
  booktitle={Stochastic programming},
  year={1980},
  PUBLISHER = {Academic Press, London-New York}
}
