UTF-32
Also known as 32-bit Unicode Transformation Format, Unicode Transformation Format – 32-bit, Unicode Transformation Format - 32-bit, UTF32, UTF_32, UCS-4, UCS4
UTF-32 (32-bit Unicode Transformation Format), sometimes called UCS-4, is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits (four bytes) per code point (but a number of leading bits must be zero as there are far fewer than 232 Unicode code points, needing actually only 21 bits). In contrast, all other Unicode transformation formats are variable-length encodings. Each 32-bit value in UTF-32 represents one Unicode code point and is exactly equal to that code point's numerical value.

The IBM® i operating system does not support UTF-32 encoding with a CCSID value. Unicode was originally designed as a pure 16-bit encoding, aimed at representing all modern scripts. Over time, and especially after the addition of over 14 500 composite characters for compatibility with established sets, it became clear that 16 bits were not sufficient for many users. Out of this arose UTF-32. Arrow rightDifferent encodings of Unicode is the algorithmic mapping from every Unicode value to a unique byte sequence.") While IBM values the use of inclusive language, terms that are outside of IBM's direct influence, for the sake of maintaining user understanding, are sometimes required. As other industry leaders join IBM in embracing the use of inclusive language, IBM will continue to update the documentation to reflect those changes.

UTF-32 (32-bit Unicode Transformation Format), sometimes called UCS-4, is a fixed-length encoding used to encode Unicode code points that uses exactly 32 bits (four bytes) per code point (but a number of leading bits must be zero as there are far fewer than 232 Unicode code points, needing actually only 21 bits). In contrast, all other Unicode transformation formats are variable-length encodings. Each 32-bit value in UTF-32 represents one Unicode code point and is exactly equal to that code point's numerical value.
The main advantage of UTF-32 is that the Unicode code points are directly indexed. Finding the Nth code point in a sequence of code points is a constant-time operation. In contrast, a variable-length code requires linear-time to count N code points from the start of the string. This makes UTF-32 a simple replacement in code that uses integers that are incremented by one to examine each location in a string, as was commonly done for ASCII. Novice programmers often vastly overestimate how useful this is.
