解决cefSharp的wpf版本里无法输入中文的问题

chromeBrowser = new ChromiumWebBrowser(Models.StaticList.ApiUrl + "/Home/Menu");
                    chromeBrowser.MenuHandler = new MenuHandler();
                    chromeBrowser.HorizontalAlignment = HorizontalAlignment.Stretch;
                    chromeBrowser.VerticalAlignment = VerticalAlignment.Stretch;
                    chromeBrowser.PreviewTextInput += (obj, args) =>
                     {
                         foreach (var character in args.Text)
                         {
                             // 把每个字符向浏览器组件发送一遍
                             chromeBrowser.GetBrowser().GetHost().SendKeyEvent((int)WM.CHAR, (int)character, 0);
                         }
                         // 不让cef自己处理
                         e.Handled = true;
                     };
                    chromeBrowser.LostFocus += ChromeBrowser_LostFocus;
                    chromeBrowser.GotFocus += ChromeBrowser_GotFocus;
                    chromeBrowser.WpfKeyboardHandler = new CefSharp.Wpf.Experimental.WpfImeKeyboardHandler(chromeBrowser);

最后一行，加粗的部分加上后就解决了
