So you have to figure out why detox, that I doesn't know and thus never have
been used, does not rename those files. Maybe because the new file (after
file name translation) already exists in directory as mentioned in the BUGS
section of the manual page. So you must ensure that all resulting file names
are unique.

And the circle starts right from the beginning.
The problem arises at that moment, where I need to feed the name
of a single file what program ever, since first there is the shell...
even when calling other programs.
Here comes escaping and/or quoting into play but the glob `detox *`, you've
specified, should work. Can you share a sample file name with funny
characters in it?
Well, at least bash is robust enough if you quote variables correctly.
$ ls -lb
total 4
-rw-r--r-- 1 dh dh 0 Feb 18 17:23 a\ "\ b\ '\ c\ #\ d
-rw-r--r-- 1 dh dh 0 Feb 18 17:27 a"b\ c
-rw-r--r-- 1 dh dh 0 Feb 18 17:26 a'b
-rw-r----- 1 dh dh 166 Feb 18 17:26 t.sh
$ cat t.sh
#!/bin/bash
TMPF=$(mktemp "/tmp/detox_wrapper.$$.XXXXXXXX")
for f in "$@"; do
touch -r "$f" "$TMPF"
detox "$f"
touch -r "$TMPF" "$f"
done
rm -f "$TMPF"
If I’m not totally wrong, the second `touch` cannot work because the
file that "$f" holds is renamed now. That’s what I mean earlier with
iterating a list or adapt Stroller’s suggestion.
I have no idea if:
modtime="$(stat -c '%Y' "$f")"
newfile="$(detox $"f")"
touch -d "@$modtime" "$newfile"
is possible instead.
