Aditya came across this in 2011 ([NTG-context] export kills hyphen symbol)[1] with the Fontin font. It wasn’t answered then. It is back if it ever left.

Here is an example:

\definefontfamily [TestFont] [rm] [Antykwa Torunska Cond] \setupbodyfont [TestFont] \setupbackend [export=maybe]% or yes, or no, or ... \setuppapersize [A7] \starttext \input ward \stoptext

If the \setupbackend statement is removed, or an invalid key is used, all is well. It fails with a valid key and any value for that key.

I am experiencing the problem of missing hyphens with this font even without \setupbackend, but cannot yet construct a working example.
