Convert a string from UTF-8 to a 32-bit fixed width representation as UCS-4. The function now performs error checking to verify that the input is valid UTF-8 (before it was documented to not do error checking). Return value: a pointer to a newly allocated UCS-4 string. This value must be deallocated by the caller.
