Thank you for your answer.

The command \definefallbackfamily seems not to be a typescript-level command.

Let us try \definefontfallback.

Let us consider the statememt:

\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic] [0x1D44E-0x1D467] [\check=yes,force=yes]

I understand it as: “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z)

of the source font with the glyphs from Baskervald italic having the same code.”

But how do you map 0x1D44E-0x1D467 of the source font to 0x61-0x7a.

How do you say: “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z) of

the source font with the glyphs 0x61-0x7a (text a-z) from Baskervald italic”?

For example something like:

\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic] [0x1D44E-0x1D467] [0x61-0x7a] [\check=yes,force=yes]

Other question: What do check, force and offset means?

Thank you.

Best regards,

Joas.
