使用俄文字母作为 hyperref 和 subfig 附录计数器时出错

我正在准备一篇俄语文本pdflatex。根据标准，附录必须用俄语大写字母编号。

但我发现如果在附录中使用子浮点数，则hyperref第二遍会产生错误pdflatex。

! Undefined control sequence.
<argument> subfigure.\T 
                        2A\CYRA .1.1

以下是重现错误的代码：

\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage{graphicx}
\usepackage[config,font=small,labelsep=period]{caption,subfig}
\usepackage[unicode]{hyperref}

%use russian alphabet for subfigure counter 
\makeatletter
  \def\thesubfigure{\textit{\asbuk{subfigure}}}
  \providecommand\thefigsubsep{,~}
  \def\p@subfigure{\@nameuse{thefigure}\thefigsubsep}
\makeatother

\begin{document}

\chapter{Sample Chapter}

\appendix
%use russian alphabet for appendix counter
\makeatletter
  \gdef\thechapter{\@Asbuk\c@chapter}
\makeatother

\chapter{Sample Appendix}

Reference \ref{fig_images}, also \ref{fig_image1} and \ref{fig_image2}.

\begin{figure}
  \centering
  \subfloat[][]{\label{fig_image1}\includegraphics[width=0.15\linewidth]{image1}}
  \hspace{0.15\linewidth}
  \subfloat[][]{\label{fig_image2}\includegraphics[width=0.15\linewidth]{image2}}
  \caption[]{\label{fig_images}
    Images:
    \subref{fig_image1}~---~first;
    \subref{fig_image2}~---~second;
  }
\end{figure}

\end{document}

有什么解决方法可以让它工作吗？或者有其他的subfig软件包吗？

答案1

已知该subfig软件包存在问题hyperref。您可以subcaption尝试使用我的软件包：


\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[config,font=small,labelsep=period]{caption}
\usepackage{subcaption}
\usepackage[unicode]{hyperref}

%use russian alphabet for subfigure counter 
\makeatletter
  \def\thesubfigure{\textit{\asbuk{subfigure}}}
  \providecommand\thefigsubsep{,~}
  \def\p@subfigure{\@nameuse{thefigure}\thefigsubsep}
\makeatother

\begin{document}

\chapter{Sample Chapter}

\appendix
%use russian alphabet for appendix counter
\makeatletter
  \gdef\thechapter{\@Asbuk\c@chapter}
\makeatother

\chapter{Sample Appendix}

Reference \ref{fig_images}, also \ref{fig_image1} and \ref{fig_image2}.

\begin{figure}
  \centering
  \subcaptionbox{\label{fig_image1}}{\includegraphics[width=0.15\linewidth]{image1}}
  \hspace{0.15\linewidth}
  \subcaptionbox{\label{fig_image2}}{\includegraphics[width=0.15\linewidth]{image2}}
  \caption[]{\label{fig_images}
    Images:
    \subref{fig_image1}~---~first;
    \subref{fig_image2}~---~second;
  }
\end{figure}

\end{document}

（我很抱歉这样无耻地自我宣传，但 subfig 与 hyperref 的问题是我编写 subcaption 包的众多原因之一。）

附录：

与 subfig 包相反，subcaption 包将仅将\thesubfigureresp.的值\thesubtable作为引用输出，因为这也是所有其他引用的行为，例如对图或章节的引用。因此，如果想要在引用中使用括号（或其他装饰元素），则必须将它们添加到那里并从标签格式中删除（这样它们就不会在那里出现两次），例如使用选项labelformat=simple。例如：


\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[config,font=small,labelsep=period]{caption}
\usepackage[labelformat=simple]{subcaption}
\usepackage[unicode]{hyperref}

%use russian alphabet for subfigure counter 
\makeatletter
  \def\thesubfigure{(\textit{\asbuk{subfigure}})}
  \providecommand\thefigsubsep{,~}
  \def\p@subfigure{\@nameuse{thefigure}\thefigsubsep}
\makeatother

\begin{document}

\chapter{Sample Chapter}

\appendix
%use russian alphabet for appendix counter
\makeatletter
  \gdef\thechapter{\@Asbuk\c@chapter}
\makeatother

\chapter{Sample Appendix}

Reference \ref{fig_images}, also \ref{fig_image1} and \ref{fig_image2}.

\begin{figure}
  \centering
  \subcaptionbox{\label{fig_image1}}{\includegraphics[width=0.15\linewidth]{image1}}
  \hspace{0.15\linewidth}
  \subcaptionbox{\label{fig_image2}}{\includegraphics[width=0.15\linewidth]{image2}}
  \caption[]{\label{fig_images}
    Images:
    \subref{fig_image1}~---~first;
    \subref{fig_image2}~---~second;
  }
\end{figure}

\end{document}

第二份附录（2011/08/19更新）：

自 2011/08/18 的 1.1 版以来，该subcaption软件包确实支持使用新选项“subrefformat=”对引用和子引用进行不同的外观和感觉。例如：


\documentclass[a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage[T2A]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[config,font=small,labelsep=period]{caption}
\usepackage[subrefformat=parens]{subcaption}
\usepackage[unicode]{hyperref}

%use russian alphabet for subfigure counter 
\makeatletter
  \def\thesubfigure{\textit{\asbuk{subfigure}}}
  \providecommand\thefigsubsep{,~}
  \def\p@subfigure{\@nameuse{thefigure}\thefigsubsep}
\makeatother

\begin{document}

\chapter{Sample Chapter}

\appendix
%use russian alphabet for appendix counter
\makeatletter
  \gdef\thechapter{\@Asbuk\c@chapter}
\makeatother

\chapter{Sample Appendix}

Reference \ref{fig_images}, also \ref{fig_image1} and \ref{fig_image2}.

\begin{figure}
  \centering
  \subcaptionbox{\label{fig_image1}}{\includegraphics[width=0.15\linewidth]{image1}}
  \hspace{0.15\linewidth}
  \subcaptionbox{\label{fig_image2}}{\includegraphics[width=0.15\linewidth]{image2}}
  \caption[]{\label{fig_images}
    Images:
    \subref{fig_image1}~---~first;
    \subref*{fig_image2}~---~second;
  }
\end{figure}

\end{document}
