syntax:

string.toLocaleLowerCase()

return:

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

description:

This method behaves exactly the same as String toLowerCase(). It is designed to convert the string to lower 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 toLowerCase().

String toLowerCase(), String toLocaleUpperCase()
