Working with locales and character encodings

Internationalization support for this product relies on that provided by the Java™ 2 Platform, Standard Edition (J2SE). Support varies by platform.

Procedure

Results

If your application produces an UnsupportedEncodingException exception, check your operating system documentation to determine if the target operating system supports the required encoding and adjust the runtime environment as needed.Use the converter.properties file as appropriate to map an unsupported character set to a supported character set. A typical converter.properties file appears below:
Shift_JIS=CP943C
EUC-JP=Cp33722C
EUC-JP=Cp33722C
EUC-KR=Cp970
EUC-TW=Cp964
Big5=Co950
GB2312=Cp1386
ISO-2022–KR=ISO2022KR
The converter.properties file implements a method for specifying a content type header field that browsers would understand (such as, SHIFT_JIS) and a writer that can output characters correctly (such as, Cp943c).

Example [Windows]

For example, on the Windows® platform, the command prompt runs in a Windows code page. Not all Windows code pages are supported by the Java platform, so it is possible to get a Java exception when running a command-line program, such as wsadmin, in an unsupported code page. To avoid exceptions, use the chcp command to explicitly set the code page to an encoding that is supported by the Java platform.
  • Before command-line calls, change the code page.

    For example, Arabic code page 720 is not supported by the Java platform, but the Arabic code page for Windows (Cp1256) systems is. Type chcp 1256

  • When starting a localized application from a command prompt, set the console.encoding property.

    For Arabic, pass the following parameter: -Dconsole.encoding=Cp1256
