It's an obtuse way of writing tr -cd 'tn -~' ...
-c means complement, -d means delete. That will delete all characters but tab, newline and the ASCII printable characters (starting with space and ending with tilde). See man ascii(7).
It will also delete printable utf-8 characters, which are used a lot on modern Unix system, so it's a bit over-the-top.
