Diacritics:

  effect     postfix   examples
  ------------------------------
  circumflex    6      a6 -> â
  breve         8      a8 -> ă
  horn          7      o7 -> ơ

  acute         1      a1 -> á
  grave         2      a2 -> à
  hook above    3      a3 -> ả
  tilde         4      a4 -> ã
  dot below     5      a5 -> ạ

  d bar         9      d9 -> đ

and postfix: E66 -> E6, a55 -> a5, etc.
