First, I'd use "sudoedit" which invokes $SUDO_EDITOR environment
variable, falling back to $VISUAL, and then $EDITOR if needed.

Since it runs vim as you rather than as root, this might solve your
problem as well.

As a side-benefit, you don't have the vulnerability that comes from
launching an editor that can shell out to root-shells.

"space:" was added to 'listchars' in v7.4.710 on 2015-04-21 by Bram.
My stock Debian install doesn't offer it so when I try your
'listchars' setting without using "space:␣" (or even "space:X" in
case the character was causing the issue), it triggers the same
message. When I try it with a recent build of vim, it works as
expected.

Are you sure that you're running the same vim binary when you run in
each case?

$ diff -u <(vim --version) <(sudo vim --version)

or perhaps

$ which vim
$ sudo which vim

-tim
