Hi,
Is there a command to produce an averaged integral sign ($\int$ with a
slash drawn across it)?
On a related note: It seems to me that \ointclockwise and
\ointctrclockwise produce results opposite to what their names would
indicate.
Thanks,
Janne Junnila

It seems wrong to me as well. It could be a problem in a mapping
internal to context (or maybe the font). char-def.lua gives, for
example,
[0x2232]={
category="sm",
description="CLOCKWISE CONTOUR INTEGRAL",
direction="on",
linebreak="al",
mathclass="limop",
mathname="ointclockwise",
unicodeslot=0x2232,
},
The Unicode slot number is correct. If you look up that Unicode character
<http://www.fileformat.info/info/unicode/char/2232/index.htm>
it has a clockwise arrow. But, as you say,
\starttext
$\ointclockwise$
\stoptext
shows an anticlockwise arrow.

I get clockwise arrow with cambria and xits, but anticlockwise arrow with
palatino and latin modern. So, it appears to be a font bug with TeX Gyre
fonts.

before we report this ... do we have the latest gyre fonts on the garden?
