UTF-8エンコーディングでTXTにシートを保存

Question

私は80バイトのラインフォーマットを必要とするレポートを生成するスクリプトを作成しています。
現在、私のスクリプトはすべてのフィールドを正しくフォーマットし、それらを単一の列に連結し、残りを削除します。この連結列には、保存時に削除できないフィールドを区切るスペースがあります。これはWindows 10のExcel 2016の64ビット版で行われています。
ファイルをUTF-8でエンコードされたテキストファイルとして保存するにはどうすればよいですか？

Answer 1

私は、Notepad ++を開いてエンコードを変更し、ファイルを保存して終了するAHKスクリプトを作成しました。私が望んでいたほどエレガントではないが、それは仕事を終わらせる。ここで
