TypeCodes don't correctly handle wchars in Anys

The wchar handling code is commented out in TypeCodeImpl.

Also, there is no minor code associated with an unknown tk int.

Sample code:

module event
{
    enum EventType
    {
        metric_created,
        metric_changed,
        metric_deleted,
        metric_error
    };

    struct MetricEvent {
        EventType type;
        wstring metric;
        wchar testa;
        wchar testb;
    };

    interface Logger {
        void process_event(in any ev);
    };
};

import event.*;
import org.omg.CosNaming.*;
import org.omg.CORBA.*;

public class Client
{

    public static void main(String args[])
    {
try{
ORB orb = ORB.init(args, System.getProperties());

            System.out.println("Unicode 3044 is: " + '\u3044');

            // get the root naming context
            org.omg.CORBA.Object objRef =
orb.resolve_initial_references("NameService");
            NamingContext ncRef = NamingContextHelper.narrow(objRef);
 
            // resolve the Object Reference in Naming
            NameComponent nc = new NameComponent("testref", "");
            NameComponent path[] = {nc};
            Logger loggerRef = LoggerHelper.narrow(ncRef.resolve(path));

// call the hello server object and print results
            Any any = orb.create_any();

            String name = "\u3044\u3048";

            MetricEventHelper.insert(any, new MetricEvent(EventType.metric_created,
                                                          name,
                                                          '\u3044',
                                                          '\u3048'));

            loggerRef.process_event(any);

} catch (Exception e) {
e.printStackTrace();
}
    }
}

import event.*;
import org.omg.CORBA.*;

import org.omg.CosNaming.NamingContextPackage.*;

public class Server extends _LoggerImplBase
{
    public void process_event (org.omg.CORBA.Any ev)
    {
        MetricEvent event = MetricEventHelper.extract(ev);

        System.out.println("Processing event chars: ");

        for (int i = 0; i < event.metric.length(); i++) {
            System.out.println("" + i + ": "
                               + Character.UnicodeBlock.of(event.metric.charAt(i)));
        }

        System.out.println("testa: ");
        System.out.println(""

        System.out.println("testb: ");
        System.out.println(""
                           + Character.UnicodeBlock.of(event.testb));

    }
    
    public static void main(String args[])
    {
try{
ORB orb = ORB.init(args, System.getProperties());

// create servant and register it with the ORB
Server loggerRef = new Server();
orb.connect(loggerRef);

// get the root naming context
org.omg.CORBA.Object objRef =
orb.resolve_initial_references("NameService");
NamingContext ncRef = NamingContextHelper.narrow(objRef);

// bind the Object Reference in Naming
NameComponent nc = new NameComponent("testref", "");
NameComponent path[] = {nc};
