In the following example the calligraphic P bumps into the following x. After some searching in the archive I found some discussions from 2012 and had the impression that this either shouldn't happen or that the behaviour could at least could be changed with \setupmathematics[italics=n]. But in my examples \setupmathematics[italics=...] doesn't do anything. Every line looks looks identical to me (the second example is from the header of xits-math.lfg). Is this behaviour expected? If yes, what should one do to get an italic correction is such cases? \setupbodyfont[xits] \starttext x${\cal P}$x\par \setupmathematics[italics=1]x${\cal P}$x\par \setupmathematics[italics=2]x${\cal P}$x\par \setupmathematics[italics=3]x${\cal P}$x\par \setupmathematics[italics=4]x${\cal P}$x\par \stoptext \setupbodyfont[xits] \starttext test $a;b;a; b; f;$ test\par \setupmathematics[italics=1] test $a;b;a; b; f;$ test\par %fontitalics \setupmathematics[italics=2] test $a;b;a; b; f;$ test\par % fontdata \setupmathematics[italics=3] test $a;b;a; b; f;$ test\par % quad based \setupmathematics[italics=4] test $a;b;a; b; f;$ test\par % combination of 1 and 3 \stoptext (xetex inserts a kern of 2.45pt after the math in latex). -- Ulrike Fischer http://www.troubleshooting-tex.de/
