Dear all,
The following example doesn't work for me:
\setupbodyfont[xits]
\starttext
\math{x\mathextensible{"2194}{hello}{}y}
\math{x\mathextensible{"21FE}{hello}{}y}
\math{\char"21FE}
\stoptext
I found the symbol which I needed there:
http://en.wikipedia.org/wiki/Arrow_%28symbol%29#Arrows_in_Unicode
and there:
http://milde.users.sourceforge.net/LUCR/Math/unimathcmds.pdf
Kind regards,
Chris

Thanks for the answer,
I wanted to use to use the mechanism described in "about.pdf" for
extensible arrows with possibly text above, under...
I've had a look at the "xits-math.tma".
Though U+2194 and U+21FE are both arrows, U+2194 has an "horizontal
part" field in contrast to U+21FE how hasn't.
So I guess the "otf" font might be the culprit.
And meddle with fonts is impossible a task.
For the present I will content myself with something like
\math{\overset{f}{-\kern-1ex\rightarrowtriangle}}
There might be a better way to achieve that in Context, I don't know.

In about.pdf on can see that U+21FE (rightarrowtriangle) is eligible
for use with \mathextensible.
When one look at the code for \mathextensible in "math-stc.mkvi", one
can see there is a mechanism of fallback.
So, since the character is implemented in "xits", there might be a way
to have "\mathextensible{"21FE} to work...
