This bug also affects macOS.  After reading the code I'd say that, even
on GNU/Linux, there are probably other corner cases where
dired-goto-file would fail:

;; FIXME: to fix this for embedded control characters etc, we
;; should escape everything that `ls -b' does.
(setq str (string-replace " " "\\ "  str)
      str (string-replace "\t" "\\t" str)
      str (string-replace "\n" "\\n" str))

For example, on GNU/Linux, ls -b outputs:

vacation\ 2022

while on macOS it outputs:

vacation 2022
