can power automate save an excel output as unicode

I have returned an excel table from office script into power automate. However when i save the file as a txt file. Notepad++ detect the file as UTF-8

Is it possible to replicate Excel's "Save As Unicode" in Power Automate,so that when i open the file in notepad++ it detects the BOM and interprets the file as UTF-16 LE

notepad++ file detection

i tried to put decodeUriComponent('%FF%FE') in front of the content(compose output) but it still returning a utf-8 file.Also tried to concat using concat(decodeUriComponent('%FF%FE'),outputs('Compose')) but still returns a utf-8 .power automate flow
