I am afraid that patch is not enough to make CharToByteUTF8.java
work fine.

Please see the attached files.

When I run 

   $ java Test test05in test05out

I expect that 512 characters should be written to test05out.
But test05out has only 341 Japanese characters (1023 bytes). 

   $ ls -al test05in test05out
   -rw-rw-r--   1 ito      ito            13 Mar  3 19:13 test05in
   -rw-rw-r--   1 ito      ito          1023 Mar  3 19:44 test05out

Attached files are here.

$ cat Test.java
import java.io.*;
public class Test {
    public static void main(String[] args) {
        try {
            char[] cbuf = new char[512];
            InputStreamReader in
                = new InputStreamReader(new FileInputStream(args[0]),"UTF8");
            OutputStreamWriter out
                = new OutputStreamWriter(new FileOutputStream(args[1]), "UTF8");
            int l = in.read(cbuf,0,cbuf.length);
            if (l > 0) {
               l--;  // chop off the line feed
               System.err.println(l + " characters");
               int i = 0;
               int j = l;
               while(j < cbuf.length) {
                  cbuf[j++] = cbuf[i++];
               }
            }
            out.write(cbuf,0,cbuf.length);
            in.close();
            out.close();
        } catch (Exception e) {
            e.printStackTrace(System.err);
