bug#35766: emacs saves utf-16 le xml files as utf-16 be

[J S]

I should say that I'm using emacs for windows.  And it's preferring saving in big endian to little endian when this is the tag:

<?xml version="1.0" encoding="UTF-16"?>

Try saving this xml file and opening it again:

<?xml version="1.0" encoding="UTF-16LE"?>

Did you try using utf-16le-with-signature?

Or maybe I don't understand the scenario: would you please describe a
full reproduction recipe, starting from "emacs -Q"?

Thanks.
