Hi,

The inode thing is exactly what I've always done in this situtation. But I just thought I'd have a play about and see if I could find another answer, and there's this approach too (which might be handier if you need to script this on a regular basis, for some really weird reason).

On up-to-date Bash on modern Linux, you can use a regex like this:

[^[:print:]]

to match non-printable characters only. I created a file with the same name as yours, and some other besides, and here's a sample session showing that regex in action.

Code:

$ ls -lb
total 0
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Right
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 15:58 Wrong\033[D\033[D\033[D\033[D\033[DRight
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong\ Filename.csv
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Wrongness
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong.txt
$ ls Wrong[^[:print:]]*
Wrong?[D?[D?[D?[D?[DRight
$ rm -v Wrong[^[:print:]]*
removed 'Wrong'$'\033''[D'$'\033''[D'$'\033''[D'$'\033''[D'$'\033''[DRight'
$ ls -l
total 0
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Right
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong Filename.csv
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:03 Wrongness
-rw-rw-r-- 1 unixforum unixforum 0 Mar 15 16:02 Wrong.txt
$

So if you absolutely needed to automate the removal of such things, this might be a useful approach if your shell and/or distro support it.
