I'm not against adding printf functions to the C standard, I've got my own formatters that work with UTF-16 and UTF-32 and I just want to add compile time checking to them really.

the point of adding new length modifiers to the standard is so the current functions can accept a UTF-16 or UTF-32 strings or characters as arguments
