the + aligns on the math axis so one can argue if the type-one variant is ok ... so we would need a smaller (less height) + then which would look visually weird
Plain TeX doesn't align the plus/minus to the math axis. Rather, the minus is aligned to the baseline, and the horizontal stroke of the plus is above the baseline. I agree that it looks a bit strange with the horizontal stroke of the plus sign not aligned with the horizontal stroke of the plus/minus. Bt it looks even more jarring to have the minus below the baseline, because the baseline is such a strong visual line.
I don't think I've ever the minus below the baseline in a math book, and it looks very wrong to my eye.
Pagella looks worse than the others, because it has a vertical gap between the minus and the plus sign, so the depth below the baseline is even larger.
(all can be achieved ... but the idea of lm/gyre fonts is to provide an acceptable consistent set ... at some point we can think of variants - or maybe the fonts have a variant already)
I realize that it's not a ConTeXt problem, but is there a ConTeXt workaround? Or better to go to the TeX guts and compute the depth of the box, then use \raise{}?

Sanjoy, the following borrows the \pm sign from Asana (which also should be like palatino), which looks more "normal". % Start example \definefallbackfamily[mainface][math][Asana Math] [range={00B1-00B1}] \definefontfamily[mainface][serif][Tex Gyre Pagella] \definefontfamily[mainface][math][Tex Gyre Pagella Math] \starttext \switchtobodyfont[pagella] Hello $\int x \pm 2 + a $\par \switchtobodyfont[asana] Hello $\int x \pm 2 + a $\par \switchtobodyfont[mainface] Hello $\int x \pm 2 + a $\par \stoptext % Stop example I guess one could do this for the other signs one don't like in TeX Gyre Pagella Math... /Mikael
