The following code demonstrates unexpected behavior of the JVM. 
Exception java.lang.InternalError is thrown as a result of method 
String.getBytes invocation on line 4.

------------------------ test.java -----------------------------------
1 class test {
2     public static void main(String args[]) throws Exception {
3 	String s = "\u3000";
4 	byte[] ba = s.getBytes("Cp933");
5     }
6 }
-------------------------- output ------------------------------------
$ java -version
java version "1.3.0beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0beta-b01)
Classic VM (build 1.3.0beta-b01, green threads, nojit)
$ java test
Exception in thread "main" java.lang.InternalError: Converter malfunction: sun.io.CharToByteCp933
        at java.lang.String.getBytes(String.java:633)
        at java.lang.String.getBytes(String.java:665)

    The same results are observed under linux java version "1.2.2",
Solaris java version "1.2.2" and Solaris java version "1.3.0rc3".
    
======================================================================

N/A

To encode this single character in Cp933 requires 4 bytes - 2 bytes plus
a shift-in and shift-out character.  getMaxBytesPerChar() needs
to be changed to return 4 since this is the max byte occupation for 
a general single char for this encoding.
