The putback for the merlin implict text conversions project (BugID 4258903)
assumes that X11-COMPOUND_TEXT is a fully supported encoding in the Sun JRE.
However, converters for this encoding have not yet been written. Attempts to
transfer text between two Solaris or Linux JVMs will generate the following
(non-fatal) exception:

java.io.UnsupportedEncodingException: X11-COMPOUND_TEXT
        at sun.io.Converters.getConverterClass(Converters.java:107)
        at sun.io.Converters.newConverter(Converters.java:138)
        at sun.io.CharToByteConverter.getConverter(CharToByteConverter.java:67)
        at java.lang.String.getCTBConverter(String.java:157)
        at java.lang.String.getBytes(String.java:685)
        at sun.awt.datatransfer.DataTransferer.translateTransferable(DataTransferer.java:647)
        at sun.awt.datatransfer.DataTransferer$4.run(DataTransferer.java:1219)
        at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:154)

        at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:121)
        at java.awt.EventDispatchThread.run(EventDispatchThread.java:99)

Once these converters are putback, the transfer of international text on
Solaris and Linux should be trivial.

Note that the encoding name 'X11-COMPOUND_TEXT' is preliminary and may need
to be changed to conform with MIME standards.
