\definefallbackfamily [documentfont] [mm] [Tex Gyre Adventor] [preset=math:lowercaseitalic] \definefontfamily [documentfont] [mm] [TeX Gyre Pagella Math]
then Tex Gyre Adventor font is used for math (\definefallbackfamily has effect).
If I have this code:
\definefontfamily [documentfont] [mm] [TeX Gyre Pagella Math] \definefallbackfamily [documentfont] [mm] [Tex Gyre Adventor] [preset=math:lowercaseitalic]
then Tex Gyre Pagella is used for math (\definefallbackfamily has no effect).
According to your answer the opposite should happen, shouldn't? I am confused.
The \definefontfamily command creates a typeface which is used to load a font but after this point you can’t make changes to it.
I see, I didn't know this.
The \definefallbackfamily command let you assign additional characters for a font but this has to happen before the font is loaded, therefore \definefallbackfamily needs before \definefontfamily in the document.
It is clear now. Thank you a lot. bcsikos
