What support does J2ME provide for internationalization (I18N)?
For J2ME CLDC apps (and so for MIDP "MIDlets" too, since MIDP requires
CLDC), you are guaranteed that necessary Unicode support is built
into the VM, that you have the
ISOLatin1 encoding available, and
that you can find out about any other available encodings using
System.getProperty method calls. Beyond that, you must do the
work in your app yourself, i.e., if you want to localize to say
Japanese, you need to check if there is a Japanese encoding
available (using the getProperty call) and then provide appropriate
ShiftJIS or other encoded text to your app if so.
For more information, please refer to the I18N/L10N section of my "Developing Wireless Applications using J2ME" talk.
