Use other field separators is possible?

[joesch2]

In my use case I would like to process entries in the following format (using the magazine CT as an example):

  @article{3|c't 13/2025,
    author = {Greta Friedrich},
    title = {Stoppt die sinnfreie KI-Schwemme!},
    journal = {c't},
    volume = {13},
    year = {2025},
    pages = {3},
}

However, BibTeX Manager cannot extract content from { }. Is it possible to allow the { } too?

Many thank's ...
