Based on the properties of the keydown event I would like to ascertain what the current charCode are?

Example.

For the keydown event when the NumPad0, D0, and Colon key is pressed I would like to know what the associated charcode is. Currently I have a map that contains the charcode associated with that keyCode or use the current if charCode is not specified.

keyCode = {
  Colon: 186,
  D0: 48,
  NumPad0: 96,
};
charCodes = {
  186: 59,
  96: 48,
};
shiftCharCodes = {
  186: 58,
  48: 41
};

Also in certain cases the keyCodes are different accross browsers?

Example.

The keydown event has different keyCode values across browsers. Colon Key (:/;) - keyCode is 59 on firefox - keyCode is 186 on IE/safari
