UCS Transformation Format—32-bit (UTF-32) is a Unicode character encoding. There is a one-to-one mapping of Unicode code points to 32-bit values, so all characters require the same number of bits. Since the largest code points can be expressed in only 21 bits, this encoding is inherently wasteful of space; UTF-8 or UTF-16 is a more efficient coding in most cases. UTF-32 does provide computational simplicity and is more often used for in-memory storage of characters than for stored documents.
