How do I check localisation/ country of player?

Hi, im think about make few languages in my game.

Of course i can set this in options but it is posibility to check automatically at start of game ?

For example when someone is playing from USA set event to change translation to ENG but when is from Poland set translation to PL?

i set in my game Global variable "LANGUAGE" so when is 0 its ENGLISH when is 1 its POLISH
