For opentype math fonts, have a look at char-def.lua. To add missing 
symbols, you need to add appropriate fields in the lua table.

The hard part is verifying the symbol to unicode slot mapping (the list at 
tralics is not always consistent with the ams list that is used by 
unicode-math package). If you know the right mappings, add a patch to 
char-def.lua and send it to the list (or the dev-context list); otherwise, 
just send the mappings and I can add them to the lua table.
