The following mapping in char-def.lua should take care of remapping - 
(0x002D) to \minus (0x2212), but it is not working.

  {
   adobename="hyphen",
   category="pd",
   cjkwd="na",
   description="HYPHEN-MINUS",
   direction="es",
   linebreak="hy",
   mathsymbol=0x2212,
   unicodeslot=0x002D,
  },

The attached patch to math-map.lua can force the remapping, but it will be 
nicer if the mathsymbol in char-def.lua worked correctly.
