Filenames with \n at the end is problematic when shared over afp

I was doing some clean up on large hard drives mounted via afp, and my process got stucked on a file like this:

find . -iname "*ins* | od -c
[...] 
0000060  [....] i   n   s   .   m   p   4      \n

I got rid of the problem manually, but now I would like to find every other problematic files on HFS+ filesystems.

How may I find those problematic filenames, and possibly everything that is known to be problematic, like brackets, backslashes, etc..

This file:

touch h$'\r'
h  \r  \n

is not found with this:
