hm, it depends on the definition of \tilde; i must look into that

\starttext

$ E_{\tilde s} $

$ E_{\def\tilde{\mathaccent"707E }\tilde s} $

{\~s}

\stoptext

Maybe some italic correction is needed here; or a tilde from an italic 
font : question for Taco, btw, in contex, \tilde in this case expands to

\mathaccent "0\purefamilyhex {mr}7E

which is the plain definition, so i wonder what goes wrong there.
