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

[J S]

For example, if I save this xml file in emacs, it saves it as utf-16 big endian:

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

If I do this in powershell (really a .net method), it saves it as utf-16 little endian (osx or windows):

[xml]$xml = get-content file.xml

$xml.save('file.xml')

What is "an application" in this context?
