Their formats are identical but their semantics is different, because UCS-4 is defined in ISO/IEC 10646, while UTF-32 is defined in Unicode Standard. Basically ISO/IEC 10646 is a standard only for characters (in normal sense), so you may not represent invalid characters in UCS-4 (e.g. 0xFFFF). On the other hand, UTF-32 disallows you to use any code value that cannot be coded in UTF-16, that is, you can use only the range [0x00000000, 0x0010FFFF]. There are some other differences, but, in brief, you can assume that they are the same, as long as you use them as internal encodings.
