I would like to, but I need to use TrueType fonts for Indian scripts in
my work that are supported in XeTeX but not (yet) in LuaTeX.

As an experiment, I tried to use the so-called 'long s' in a Fraktur
font, which comes out well in XeTeX with LaTeX, but I must be doing
something wrong in ConTeXt.

Example:

% The 'StylisitcSet 11' in the font UnifrakturMaguntia should contain
the so-called 'long s'.
% Somehow it doesn't work.

\starttext

\definetypeface [hauptfont] [rm] [Xserif] [Charis SIL]
\definetypeface [schoenfont] [rm] [Xserif] [UnifrakturMaguntia]
[default] [features={StylisticSet=11}]

\switchtobodyfont [hauptfont]
Dies ist mit Features, denke ich.

{\switchtobodyfont [schoenfont] Und jetzt schreiben wir etwas in
Fraktur, das ist ja schöner.}

\stoptext
