String bianma=new String(b,"utf-8");

         byte[] orig = toByte.convertAll ( str.toCharArray () );

char[] dest = new char[ orig.length ];

for ( int i = 0; i < orig.length; i++ )

        dest[ i ] = ( char ) ( orig[ i ] & 0xFF );
    out1.println("1"+ str);
    out1.println("2"+dest);
    out1.println("3"+bianma);

out1.close();

socket.close();

就是将一段中文发送给服务器端，但是由于编码问题对方接收的都是乱码，在网上看过很多关于unicode转换的方法，也不能解决这个问题，是在无助，请大家帮忙了，谢谢！！
