biber 输入错误

我在使用 biblatex 时遇到一个奇怪的错误，使用 biber 作为后台引擎。我的最小示例是：

\documentclass {scrreprt}
\usepackage[T1]{fontenc}
\usepackage[german]{babel}
\usepackage{lmodern}
\usepackage[backend=biber]{biblatex}
\addbibresource{⁨lib.bib}
\begin{document}
asdf  \cite{heupel_international_2018}
\printbibliography
\end{document}

对应的bib文件是：

@article{heupel_international_2018,
  langid = {english},
  title = {International Organisations and Human Rights: {{What}} 
Direct Authority Needs for Its Legitimation},
  volume = {44},
  issn = {0260-2105, 1469-9044},
  url = {https://www.cambridge.org/core/journals/review-of- 
 international-studies/article/international-organisations-and-human- 
 rights-what-direct-authority-needs-for-its- 
 legitimation/5C605ECBAA1E2667D07BBFB3EACDA3CA},
  doi = {10.1017/S0260210517000420},
  shorttitle = {International Organisations and Human Rights},
 number = {2},
  journaltitle = {Review of International Studies},
  urldate = {2018-08-12},
  date = {2018-04},
  pages = {343-366},
  keywords = {Legitimacy,International Organizations,Authority,Human 
Rights,Legitimation},
  author = {Heupel, Monika and Hirschmann, Gisela and Z\"urn, Michael},   
}

我给出了错误：“INFO - 正在寻找 bibtex 格式文件'\GenericError {(inputenc) }{Package inputenc 错误：Unicode 字符 \GenericError {(inputenc) }{Package inputenc 错误：Unicode 字符 (U+2068)\MessageBreak 未设置为用于 LaTeX}”

答案1

{和l之间有一个 U+2068 控制字符

\addbibresource{⁨lib.bib}

仅使用可见字符重新输入该行，即

\addbibresource{lib.bib}
