syntax:

string.toLocaleUpperCase()

return:

string - a copy of a string with each character converted to upper case.

description:

This method behaves exactly the same as String toUpperCase(). It is designed to convert the string to upper case in a locale sensitive manner, though this functionality is currently unavailable. Once it is implemented, this function may behave differently for some locales (such as Turkish), though for the majority it will be identical to toUpperCase().

see:

String toUpperCase(), String toLocaleLowerCase()
