|

|
<div><p>UTF-32 is an encoding of Unicode in which each character is composed
|
||
|
|
of 4 bytes.</p>
|
||
|
|
<p>The operating system does not support UTF-32 encoding
|
||
|
|
with a CCSID value.</p>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>UTF-32 allows characters to be encoded as 4 bytes at any code point from
|
||
|
|
00000000 to 0010FFFF. For example, the string <em>ABC</em> in UTF-32 is encoded
|
||
|
|
as <samp class="codeph">x"000000410000004200000043"</samp>.</p>
