Dear list,
I am unhappy with how some fonts kern particular subscripts. For example in
the default Latin Modern, subscripts to the Greek capital gamma could use some
negative kerning. Because I can't (and don't want to) fix the font, I thought
that I could patch the font on-the-fly in ConTeXt.
The usual approach with fonts.handlers.otf.addfeature works well in math mode,
but does not extend into subscripts (MWE below). Is there a method to adjust
subscript kernings? Could this be done using mathkerns? Latin Modern doesn't
have any but maybe they can be added on the fly.
Cheers, Henri

$\Gamma0$ % works fine :)
$\Gamma_0$ % doesn't work :(
