在 biber 中,更新宏时 idemgender 未解析 cite:idem

在 biber 中,更新宏时 idemgender 未解析 cite:idem

参考问题,我发现更新宏时出现问题cite:idem,因为编译器无法解析变量 idemgender

以下是从所引用的问题中得出的一个例子。宏cite:idem被更新为以小写字母打印其参数。

\documentclass{article}

\usepackage[italian]{babel}

\usepackage[backend=biber, citestyle=verbose-trad2]{biblatex}

\begin{filecontents*}{\jobname.bib}

@article{bollman1966cannophori, 
  author   = {Demidov, S.S.},
  title= {N.V. Bugaev e lo sviluppo della scuola matematica moscovita},
  journaltitle = {Ricerche di storia della matematica},
  date = {1985},
  number   = {XXIX},
  pages= {113-124},
}

@incollection{bollman1998romische, 
  author = {Demidov, S.S.},
  title= {N.V. Bougaiev et la creation de l'Ecole de Moscou},
  date = {1985},
  booktitle= {Mathemata.},
  editor   = {Folkerts, M.},
  publisher= {Steiner Verlag},
  location = {Stuttgart},
  pages = {651-673},
}

\end{filecontents*}

\addbibresource{\jobname.bib}

\providecommand*{\mkidem}[1]{\textsc{#1}} 
% substitute: \mkidem for \mkibid
\renewbibmacro*{cite:idem}{\bibstring[\mkidem]{idem\thefield‌{gender}}\setunit{\p‌​rintdelim{nametitled‌​elim}}}

\begin{document}
First \footcites{bollman1998romische}{bollman1966cannophori}

And second\footcite{bollman1966cannophori}
\end{document}

使用 LuaLateX 编译的输出给出以下脚注:

如您所见,文档打印的不是“Idem”,而是令牌性别认同

问题中的代码包含一些不可见的字符,这会使事情变得混乱。当从评论中复制代码时,我在这个网站上多次看到过这种效果。

\thefield具体来说,和之间有一个零宽度非连接符 (U+200c),在in之后和 in 之后也有{gender}一个零宽度非连接符 (U+200c) 和一个零宽度空格 (U+200b) 。如果您查看代码突出显示,您会发现 有点不对劲: 所有的 都应该是蓝色的,但在问题的代码中只有是蓝色的。p\printdelimdnametitled‌​elimp\printdelim\p

像这样的网站https://w3c.github.io/xml-entities/unicode-names.html可以极大地帮助找到那些讨厌的隐形字符。

当我删除不需要的不可见字符时,下面的工作就正常了

\documentclass{article}
\usepackage[italian]{babel}
\usepackage[backend=biber, citestyle=verbose-trad2]{biblatex}

\providecommand*{\mkidem}[1]{\textsc{#1}} 

\renewbibmacro*{cite:idem}{%
  \bibstring[\mkidem]{idem\thefield{gender}}%
  \setunit{\printdelim{nametitledelim}}}
