Journal title `Künstliche Intelligenz` causes jabbrv to lock up

[logological]

jabbrv doesn't seem to like the journal title Künstliche Intelligenz; processing a bibliography entry with such a title causes pdflatex to lock up. Running pdflatex + biber + pdflatex with an up-to-date TeX Live 2024 on the following minimal example demonstrates the problem:

\documentclass{article}

\usepackage{biblatex}
\usepackage{jabbrv}
\begin{filecontents*}{\jobname.bib}
@article{sokol2020one,
  title={foo},
  author={bar},
  journal={Künstliche Intelligenz},
  volume={1},
  number={2},
  year={2020},
}
\end{filecontents*}

\addbibresource{\jobname.bib}
\begin{document}
\cite{sokol2020one}
\printbibliography
\end{document}

A lot of latex tools do not support unicode very well, have you tried to use the traditional typeset version?:

K\"unstliche Intelligenz

Yes. The problem does not seem to have anything to do with the ü. I see the same behaviour with \"u, {\"u}, etc.

Interesting, I didn't try with biber before (I can confirm that I see the same behavior with biber). I'm not sure if this is a biber problem or a jabbrv problem, but I'll try to take a look later.
