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… 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 « : » in front of the equal sign « = », in the combination « := » (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) := -(u|x) := - \langle u, x \rangle
\stopformula
\stopformula
\startformula
f : A \longrightarrow B
\stopformula
\stoptext

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

Best regards: Otared
