The main reason people want to use wchar_t is because they want to use a fixed width presentation of characters. Just using UCS-4 doesn't give you that if you ever want to support Level 2 and higher. It also highlights UCS-4 is not that state independent as it is often thought to be. That is again something undesirable.
