Dear list.
Please your help
I've troubles to use this code from Wolfgang.
\definefontfamily [minionmath] [rm] [Minion Pro]
\definefallbackfamily [minionmath] [mm] [Minion Pro] [preset=math:lowercasenormal]
\definefallbackfamily [minionmath] [mm] [Minion Pro] [preset=math:lowercaseitalic]
\definefallbackfamily [minionmath] [mm] [Minion Pro] [preset=math:lowercasebold]
\definefallbackfamily [minionmath] [mm] [Minion Pro] [preset=math:lowercasebolditalic]
\definefontfamily [minionmath] [mm] [TeX Gyre Pagella Math]
\setupbodyfont[pagella]
\starttext
\startformula
{\tf xyz} xyz {\bf xyz} {\bi xyz}
\stopformula
\switchtobodyfont[minionmath]
\startformula
{\tf xyz} xyz {\bf xyz} {\bi xyz}
\stopformula
\stoptext
It seems that \definefallbackfamily doesn't works like before.
What is the right way to use \it, \bf, etc. in maths?
