多语言书目和自动索引

Question

我使用 biblatex 来构建：

• 一个自动索引参考书目中所引用的作者。
• 单一语言的参考书目，标点符号规则取自 langid每个条目。

正如在最后一个答案的评论中所讨论的那样，这些解决方案非常独立地工作，但是当我尝试混合两者时出现以下错误：

! Undefined control sequence.
\blx@nameparser@i ...pandafter {\mblx@currentname
}{\mblx@exemptfields } {\b...
l.142 \footcite{compagnon}

我尝试“免除”该author字段的补丁，但没有成功。这可以实现吗？还是补丁会变得不合理？

下面是一个测试代码，注释掉允许建立索引的长补丁：

Answer 1

代码在多语言文献中的标点符号规则可能不仅应该修补\printnames和\printlist，还应该\indexnames修补和\indexlist。（现在那里也已经修复了。）

以下代码应该可以编译。
