That's correct, kind of. The setting isn't 'mine', its the emacs
default. In both emacs 26.1 (debian) and emacs-snapshot (v28),
file-name-coding-system defaults to nil, and
default-file-name-coding-system defaults to utf-8-unix, so we have:
file-name-coding-system => nil
(default-value file-name-coding-system) => nil
default-file-name-coding-system => utf-8-unix
Anybody besides me find that amusing? It reminds me of Bug report #43294
in that both seem intentionally designed to cause confusion and trip-up
developers.

The FreeDesktop.org Trash specification[1] says about the trash restore
PATH:
"The value type for this key is “string”; it SHOULD store the file
name as the sequence of bytes produced by the file system, with
characters escaped as in URLs (as defined by RFC 2396, section 2)."
The RFC says (section 2.1):
"... there is currently no provision within the generic URI syntax to
accomplish this identification ... It is expected that a systematic
treatment of character encoding within URI will be developed as a
future modification of this specification."
