Thank you again. Now I am even more confused.


3. I found that if I write \definefontfamily     [docuf] [mm] [TeX Gyre Pagella Math]
before \definefallbackfamily lines, the latter have no effect. Is this normal?
Shouldn't the order of definition lines be indifferent?

The fallbackfamily settings are applied to a typeface and the 
\definefontfamily commands creates the typeface, without \definefontfamily the
fallbacks are never used because there is no font which can use the settings.


Sorry, but I don't understand the answer. If I have the code:

\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. 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.
