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
