I just wanted to bring this topic up again since it is still
reproducible with ConTeXt MKIV 2011.11.25 21:29.

Yes, it does.

Using XITS it does also work although in display math mode(?) ∫ and
$\intop$ are not scaled.
I use the following example.
\setupbodyfont[xits]
\setupinteraction[state=start]
\useurl[context2008][http://wiki.contextgarden.net/Context_2008.04.10][][\ConTeXt\
version 4/10/2008]
\starttext
Using the NEO keyboard layout several math symbols can be inserted
directly like $∫$ or $∩$.
But $\int$ by \type{\int} and $∫$ by UTF-8 character look differently.
As Mojca pointed out \type{\intop} is also not type set correctly: $\intop$.
This suggests that it is a problem with the Latin Modern font. \type{\intop}
was added in \from[context2008].

Is there a chance to fix `\intop` in Latin Modern (and XITS).
Would it be a good idea to map ∫ to $\int$ instead of `\intop`? Do
people use `\intop` a lot?
Thanks,
Paul
PS: Although this seems font related, some more information just in
case. ∫ has the Unicode number(?) #222B [1] and `xev` returns the
following.
