Supported Encodings - JDK 5 Documentation v1.4.1, Java 2 SDK 英文文档

Supported Encodings

The classes java.io.InputStreamReader, java.io.OutputStreamWriter, java.lang.String, and classes in the java.nio.charset package 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 and the class description for java.nio.charset.Charset list the encodings that any implementation of the Java 2 platform, Standard Edition, v. 1.4.1 is required to support.

Sun's Java 2 Software Development Kit, Standard Edition, v. 1.4.1 for all platforms (Solaris^TM operating environment, Linux, and Microsoft Windows) and the Java 2 Runtime Environment, Standard Edition, v. 1.4.1 for Solaris and Linux support all encodings shown on this page. Sun's Java 2 Runtime Environment, Standard Edition, v. 1.4.1 for Microsoft 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/charsets.jar file) supports all encodings shown on this page.

The following tables show the encoding sets supported by J2SE 1.4.1. The canonical names used by the new java.nio APIs are in many cases not the same as those used in the java.io and java.lang APIs.
