SendInputについて云々
エミュレーションで文字列送信で全角が送信できない
文字列送信ノードも安定しない
LCtrlとRCtrlの区別が出来ない
このような問題に対応する方法がテーマです。
まずは文字列送信について

長いですがpowershellスクリプトです
ポイントはKEYEVENTF_UNICODEでこれを付与することによってunicode送信できます
WinActorから使用する場合SetForegroundWindowしないと安定しなかったので操作対象のhWndが必要です
WinActorから使用する場合は
ウインドウハンドル取得で hWnd を取得
文字列連結で -ExecutionPolicy RemoteSigned -File スクリプトのパス hWnd 送信文字列
を組み立て（ExecutionPolicyはお好みで）
コマンド実行でpowershell実行オプションに上記で連結した文字列
LCtrl送信

LCtrl と RCtrl の違いは KEYEVENTF_EXTENNDKEY 及び ScanCode の部分です
長くなりましたが、まあ興味があるひと向けです
