Hello,
I'm just wonderding if there is a way to switch to an OpenType Math font (referred to by name or filename, without any predefined typescript) with some stylistic alternative in the middle of the document, like in the LaTeX example:
Sure, when Khaled added alternates to xits we also added support for it to mkiv.
\setupbodyfont[xits]
But this requires a whole typescript. So there is no way to say something equivalent to \font\a=Asana-Math.otf \a without the need to create a lfg file & so on? Anyway, your example with Asana broke a compilation, so at least I was able to realize that I was missing the otf font, whereas yesterday it was simply ignoring the fact that the font was missing and has typeset everything in TeX Gyre I think.
\starttext
\unexpanded\def\mathaltcal{\mathalternate{cal}\cal}
And how do I know what is an equivalent of StylisticSet=4 in Lucida? Would this be something like italic = { feature = 'ss01', value = 1, comment = "Mathematical Alternative Italic" }, where \mathalternate{italic} works as +ss01, but the ss04 not because it has not been defined in lucida-opentype-math.lfg?
$ABC$ $\cal ABC$ $\mathalternate{cal}\cal ABC$ $\mathaltcal ABC$
