To channel Rowland, this isn't a bug report, this is an
anecdote :-).

Here's what I did to show this doesn't happen.

$ mkdir /tmp/chartest
$ touch /tmp/chartest/fil\\e.dat
$ ls -l /tmp/chartest/
total 0
-rw-rw-r-- 1 user user 0 Jan  1 18:52 'fil\e.dat'

Edit /usr/local/samba/etc/smb.conf, add:

[chartest]
	path = /tmp/chartest
	guest ok = yes
	read only = no

Restart smbd. Run:

$ /usr/local/samba/bin/smbclient //127.0.0.1/chartest -Uuser%password -mSMB3
smb: \> ls
   .                                   D        0  Fri Jan  1 18:52:10 2021
   ..                                  D        0  Fri Jan  1 18:51:38 2021
   FI7KDO~J.DAT                        N        0  Fri Jan  1 18:52:10 2021

IF YOU WANT ME TO INVESTIGATE THIS IS NEED A SIMILAR
LEVEL OF DETAIL (sigh). But I *know* you *know*
this...
