No, your comparison is not fair.

You're using "env" to begin with, which alters processing of parameters.
But I can't reproduce your case. The result is definitely does not contain the quotes.

chcp 65001
set LANG=ru_RU.UTF-8
env LANG=ja_JP.UTF-8 touch 'あああ'

It creates exactly the name I'd expect, even though I can't see it in console.
But Explorer don't lie and shows it proper.
