I know what you mean. I did not express myself very specific. What I
meant is to alias cat to something else that specifically turns off
control sequences.

Like alias cat='sequence off; cat' something like that

Somebody already mentioned there is cat -v to show nonprinting
characters with notation ^- and M- so that may be the solution and I
may be wrong there.

I am often using cat to view files and for some remote files I have to
put attention.
