Hi,

Thanks Hraban for the information and the link to the article by Hans =
and Mikael about the math fonts in Lucida.

I very much appreciated that article: one sees how the handling of =
almost impercebtile details in ConTeXt make us to adhere to and love =
LuaMetaTeX=E2=80=A6 So a great thank you to Hans and Mikael for all this =
work!

Regarding the details of vertical alignment in math, I wonder whether =
the column =C2=AB : =C2=BB in front of the equal sign =C2=AB =3D =C2=BB, =
in the combination =C2=AB :=3D =C2=BB (used to define for instance a new =
variable) should be alos centered around the math axis, as explained in =
the article. For instance in the following example

\setupbodyfont[lucidaot,12pt]
\starttext
\startformula
f(x) :=3D -(u|x) :=3D - \langle u, x \rangle
\stopformula
\stopformula
\startformula
f : A \longrightarrow B
\stopformula
\stoptext

it seems to me that the lower dot (or square=E2=80=A6) in the semicolumn =
of the first formula (in front of the equal sign) is lower than in the =
second formula.

Best regards: Otared
