That would be wrong.  EncoderUTF8 is used to convert 16-bit Unicode
to the *external* UTF8 encoding used for files etc.  Not the Java
pseudo-UTF8.

I can only think of one reason why you'd want to create the Java
pseudo-UTF8 format:  when writing a Java class file.  Implement
that however you wish, but don't change the behavior of EncoderUTF8.
You could add a flag to EncoderUTF8 file to enable "Java-style UTF8",
but it can't be the default.
