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 platform. The class description for java.nio.charset.Charset lists the encodings that any implementation of the Java Platform, Standard Edition 6 is required to support.

Sun's Java SE Development Kit 6 for all platforms (SolarisTM operating environment, Linux, and Microsoft Windows) and the Java SE Runtime Environment 6 for Solaris and Linux support all encodings shown on this page. Sun's Java SE Runtime Environment 6 for Windows may be installed as a complete international version or as a European languages version. The JRE installer by default installs a European languages version if it recognizes that the host operating system only supports European languages. If the installer recognizes that any other language is needed, or if the user requests support for non-European languages in a customized installation, a complete international version is installed. The European languages 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 Java SE 6. 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.
