Supported Encodings

The classes java.io.InputStreamReader, java.io.OutputStreamWriter, and java.lang.String can convert between Unicode and a number of other character encodings. The supported encodings vary between different implementations of the Java 2 platform. The java.lang package specification lists the encodings that any implementation of the Java 2 platform, Standard Edition, v. 1.3 is required to support. Note that some of the required encodings have canonical names in Sun's implementations that are different from the names shown in the specification. The required names of these encodings are supported through an alias mechanism: US-ASCII maps to ASCII, ISO-8859-1 to ISO8859_1, UTF-8 to UTF8, UTF-16BE to UnicodeBigUnmarked, and UTF-16LE to UnicodeLittleUnmarked.

Sun's Java 2 Software Development Kit, Standard Edition, v. 1.3.1 for Windows or Solaris and the Java 2 Runtime Environment, Standard Edition, v. 1.3.1 for Solaris support all encodings shown on this page. Sun's Java 2 Runtime Environment, Standard Edition, v. 1.3.1 for Windows comes in two different versions: US-only and international. The US-only version only supports the encodings shown in the first table. The international version (which includes the lib\i18n.jar file) supports all encodings shown on this page.
