Biber：带有宏 \textbf{} 的简写排序不同

Question

.bib如果我将文件中的简写从更改XYZ为\textbf{X}YZ参考书目中的顺序就会改变。

我怎样才能使用以 a 开头的速记\textbf（以粗体显示某些字母）而不破坏排序顺序？

我们得到

与不使用简写的方式相比

Answer 1

biblatex了解该领域sortshorthand。biblatex文档解释（§2.2.3特殊字段，第 30 页）：

[ sortshorthand] 类似于sortkey但用于简写列表。如果存在，则在对简写列表进行排序时biblatex使用此字段而不是。shorthand如果简写字段包含带有格式化命令（例如\emph或 ）的简写，则这很有用。\textbf

对于alphabetic排序方案anyt和anyvt biblatex不使用sortshorthand（因为这基本上意味着跟踪labelalpha和sortlabelalpha将根据相同规则构建的，但优先于sort...字段）。

使用标准设置（如果后者存在则设置labelalpha为），在排序方案之前添加就足够了。shorthand\field{sortshorthand}\field{labelalpha}

MWE 重新定义了这两种排序方案，但如果您只使用其中一种，则可以删除另一种。
