Further Information about Character Encoding<br />

Note – UTF-16 depends on the system’s byte-ordering conventions. Although in most systems,<br />

high-order bytes follow low-order bytes in a 16-bit or 32-bit “word,” some systems use the<br />

reverse order. UTF-16 documents cannot be interchanged between such systems without a<br />

conversion.<br />

Further Information about Character Encoding<br />

<strong>The</strong> character set and encoding names recognized by Internet authorities are listed in the IANA<br />

character set registry at http://www.iana.org/assignments/character-sets.<br />

<strong>The</strong> <strong>Java</strong> programming language represents characters internally using the Unicode character<br />

set, which provides support for most languages. For storage and transmission over networks,<br />

however, many other character encodings are used. <strong>The</strong> <strong>Java</strong> 2 platform therefore also supports<br />

character conversion to and from other character encodings. Any <strong>Java</strong> runtime must support<br />

the Unicode transformations UTF-8, UTF-16BE, and UTF-16LE as well as the ISO-8859-1<br />

character encoding, but most implementations support many more. For a complete list of the<br />

encodings that can be supported by the <strong>Java</strong> 2 platform, see http://java.sun.com/javase/6/<br />
