Example

In the example we load the moustache brackets from XITS Math because they are not available in Latin Modern Math, which is the default math font. Of course, the technique also works for text fonts.

\definefontfallback [xits-fallback] [file:xits-math.otf] [023B0,023B1]

\definefontsynonym [MathRoman] [modern] [fallbacks=xits-fallback]

\starttext

$\lmoustache a \rmoustache$

\stoptext

(The example does not work on the Wiki due to the lack of the XITS font.)
