I see. I've noticed lang-us.lua has a list of exceptions in it:
  ["exceptions"]={
   ["characters"]="abcdefghijlmnoprstuyz",
   ["data"]="as-so-ciate as-so-ciates dec-li-na-tion oblig-a-tory 
phil-an-thropic present presents project projects reci-procity 
re-cog-ni-zance ref-or-ma-tion ret-ri-bu-tion ta-ble",
   ["length"]=168,
   ["n"]=14,
  },

Would it be possible to add more exceptions to that list as they come 
up? Or is that inappropriate?
