cocos2dx 3.x 解决输入框(TextField,TextFieldTTF) 输入中文变乱码的问题

//原来的方法如下：
void GLView::onGLFWCharCallback(GLFWwindow *window, unsigned int character)  
{  
    IMEDispatcher::sharedDispatcher()->dispatchInsertText((const char*)&character, 1);  
}

//修改后的方法如下：
void GLView::onGLFWCharCallback(GLFWwindow *window, unsigned int character)
{
   if (character < 128)
        IMEDispatcher::sharedDispatcher()->dispatchInsertText((const char*)&character, 1);
    else
    {
        char szUtf8[8] = { 0 };
        int nLen = WideCharToMultiByte(CP_UTF8, 0, (LPCWSTR)&character, 1, szUtf8, sizeof(szUtf8), NULL, NULL);
        IMEDispatcher::sharedDispatcher()->dispatchInsertText(szUtf8, nLen);
    }
}
