Hi Jack,

I tested your example both with Pagella and Lucida OT: indeed typesetting with the latest LMTX, with Pagella the math italic « f » runs into the right bar of « |f| ».

However the result with mkiv is correct.

I am attaching the PDF output with LMTX.

Best regards: Otared

Hi,

I've been having some trouble with ConTeXt not typesetting math correctly when using the Pagella font (I do not know if the same issue occurs with other fonts as I haven't tested them).

If I compile with LMTX, the spacing between letters becomes very small so that when I type "|f|", for example, the second "|" intersects the f and looks rather ugly. However, compiling with the --luatex switch fixes these issues and the math looks nice again.

Can anybody else replicate this issue, and does anybody know why it is happening?

This the code I used to test:

\setupbodyfont[pagella]

\starttext
\startformula
|f| = \sqrt{\int_0^1 |f(t)|^2 \text{d}t}
\stopformula
\stoptext

Jack
