当书名以引号结尾时，biblatex 标点符号问题

Question

1. 这芝加哥格式手册规定了美式标点符号：句号和逗号应位于右引号之前（§ 6.9）。
2. 它还规定书名中的标题应该用双引号引起来（§14.102）。
3. 因此，一些书名会以结束的双引号结尾。

不幸的是，该biblatex-chicago包（和可能的biblatex）似乎没有考虑到上述规则 1 和 2 的组合。在下面的最小工作示例中，第三个引用导致在结束引号后有一个逗号，而参考书目在结束引号后有一个句号。两者都应在结束引号之前。我该如何解决这个问题？

\documentclass{book}
\usepackage{xltxtra}
\usepackage{etoolbox}
\usepackage{etex}
\usepackage{keyval}
\usepackage{ifthen}
\usepackage{url}
\usepackage[style=american]{csquotes}
\usepackage{polyglossia}
\usepackage{verbatim}
\usepackage[notes]{biblatex-chicago}

\setdefaultlanguage{english}
\begin{filecontents}{book.bib}
@book{key1,
   author = {Marty McFly},
   title = {This Book Title Ends in \enquote{Quotation Marks}},
   location = {Oxford},
   publisher = {Oxford University Press},
   year = {1976}
}

@book{key2,
   author = {John Updike},
   title = {Some Title},
   location = {Cambridge, MA},
   publisher = {Harvard University Press},
   year = {2002}
}
\end{filecontents}
\addbibresource{book.bib}

\begin{document}

Here I cite a book whose title ends in a closing quotation mark\autocite[55]{key1}.
I follow this up with an unrelated citation\autocite[xi]{key2}.
Here I cite the first work a second time, which results in a short reference\autocite[75]{key1}, which unfortunately misplaces the period.

\printbibliography

当我的后记以右引号结尾时，也会出现此问题：

\autocite[s.v. ``word'']{dictionary}

但我可以在附注中添加句号来解决。

Answer 1

您可以使用biblatex/ csquotesquotation 命令\mkbibquote。因此您的示例将如下所示

title = {This Book Title Ends in \mkbibquote{Quotation Marks}}

不幸的是，这个解决方案的代价是使.bib文件在某种程度上依赖于biblatex。

另请参阅biblatex-chicago文档关于第 49-50 页\mkbibquote、第 4 页以及实际上很多其他地方（这是第 4 页）：

[I]如果您的.bib文件中目前有引用材料，并且正在使用\enquote或标准 LaTeX 机制，那么最简单的程序始终是使用，\mkbibquote以确保标点符号正确。
