Do you mean functions for translating human language?
The answer to that is no.
As far as I know there are no Tier 1 functions for determining any user type settings for a device or platform.
About the only thing I can suggest is storing displayed strings in different languages in text files that have an index that you use to select the string and then let the user select the language as an option and load the correct language file.
You could use GetStringToken to split the lines on ':' (or some other character)
A file might look something like this -
game_text_en.txt:
1:Hello player!
2:Goodbye player!
game_text_sp.txt:
1:Hola jugador!
2:Adiós jugador!
I do this for one of my client's sites and it is a royal pain in the butt.
