I'm having a strange error with biblatex using biber as a backengine. My minimal example is:

\documentclass {scrreprt}
asdf  \cite{heupel_international_2018}

And the correstponding bibfile is:

  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- 
  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 
  author = {Heupel, Monika and Hirschmann, Gisela and Z\"urn, Michael},   

I gives me the error: "INFO - Looking for bibtex format file '\GenericError {(inputenc) }{Package inputenc Error: Unicode character \GenericError {(inputenc) }{Package inputenc Error: Unicode character ⁨ (U+2068)\MessageBreak not set up for use with LaTeX}"

  • @moewe that's odd as there is a U+2068 (FIRST STRONG ISOLATE) character in the posted code. – David Carlisle Oct 19 '18 at 12:34

    @DavidCarlisle Makes sense, I always replace the \addbibresource with a filecontents-generated \addbibresource{\jobname.bib}. And I really didn't expect the problem to come from the document ... – moewe Oct 19 '18 at 12:36

    @moewe I pasted the OPs code into w3c.github.io/xml-entities/unicode-names.html :-) – David Carlisle Oct 19 '18 at 12:36

    Note that the line breaks in the URL field will be encoded as spaces, you should remove them. The issn field should only hold one ISSN (just like isbn, doi and url only hold one item). I'd also write Zürn instead of Z\"urn. german will give you alte Rechtschreibung, if you want neue Rechtschreibung you need ngerman. – moewe Oct 19 '18 at 12:37

    Instead of title = {International Organisations and Human Rights: {{What}} Direct Authority Needs for Its Legitimation}, and shorttitle = {International Organisations and Human Rights}, I'd go with title = {International Organisations and Human Rights}, and subtitle={What Direct Authority Needs for Its Legitimation},. – moewe Oct 19 '18 at 12:40

You have a U+2068 control character between the { and l in


retype that line with just the visible characters, i.e.

  • You're right. Deleting the entire line and retyping it worked. Thanks alot! – Teppichporsche Oct 19 '18 at 13:33
