Pdflatex 拒绝处理带有井号的 .bib 文件#

Question

Pdflatex（不是 Biber）在howpublishedbbl 中抱怨有关 hastag 符号的行。当我删除 hastag 时，它确实可以编译，但出了什么问题，如何首先防止这种情况发生？

Illegal parameter number in definition of \NewValue. ...s://tools.ietf.org/html/rfc3168#page-11}}

.bib即使您将未转义的井号隐藏在\url命令中，它也不能出现在文件的非逐字字段中，通常它不会造成危害。

最好在专用url字段中提供 URL（无论如何您似乎已经这样做了），它可以处理诸如#和朋友之类的恶意字符，因为它使用特殊的逐字模式。

然后，您可以在造成任何损害之前使用 Biber 的源映射删除它。如果我们还没有字段，howpublished我们甚至可以尝试从该字段中恢复 URL 。howpsublishedurl

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=howpublished, match=\regexp{\A\\url\{(.+)\}\Z}, final]
      \step[fieldset=url, fieldvalue={$1}]
      \step[fieldset=howpublished, null]
    }
  }
}
