So searching through coreutils I find this old report:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23024

Which huh, does mention this in the ls manual:
| If you use a quoting style like ‘--quoting-style=c’ (‘-Q’) that

| ‘--quoting-style=literal’ (‘-N’) option on the command line, or
| else be prepared to parse the escaped names.
Then it references a commit mentioning an emacs fix:
https://github.com/emacs-mirror/emacs/commit/e4adb6
which however seems to apply to tramp only.
