Subject: Re: \mathextensible{"21FE}
Date: Fri, 25 Apr 2014 00:43:34 +0200 [thread overview]
Message-ID: <CAGMMSTBf3W1ihfPH8cEfiYOUSm_U=b2D98KePPbyVZF21TdsGQ@mail.gmail.com> (raw)

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...
