Here is a ticket I hope we can close as invalid. I don't have that
power, but it would be nice if a couple people could make sure this is
true (esp. people who have lots of folders and files with non-ASCII
names). It could be a really easy one to close otherwise, at most
reverting a tiny bit of sage-env.
