On a related note: It seems to me that \ointclockwise and \ointctrclockwise produce results opposite to what their names would indicate.

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. Aditya
