Im using for old hebrew and old greek text special fonts with fontspec. How can i use this also in the footnotes and in den bibliography? There are only single hebrew words in 3 of the booktitle.
Im using Lulatex and Biblatex with biber.
I found a way to set the complete bibliography in Esra SIL with
\renewcommand*{\bibfont}{\hebfont}
but this gives me an error
/usr/share/texmf-dist/tex/latex/biblatex/biblatex.def
! LaTeX Error: Command \bibfont already defined.
