        \begin{tabular}{l@{\hspace{.75em}}l}
            Autor:      & Jean-Michel Clairand\\[4ex]
            Director:   & D. Carlos Álvarez Bel\\[.5ex]
                                \end{tabular}
        }
    }

\begin{document}

\frontmatter

当我编译时，出现以下错误：

未指定 \title。\cleardoublepage

包 inputenc 错误：在输入编码“utf8”中，使用的键盘字符未定义（inputenc）。 \cleardoublepage

初始模板未使用 utf8，但我在命令 \usepackage[utf8]{inputenc} 中对其进行了更改，因为我需要它。问题出在 \maketitle 命令中，因为当我删除它时，它会编译它，但没有封面页。我如何使用 \maketitle 命令而不出现这些错误？
