Actually, tab and NL are not translated. From the man page:-v, --show-nonprinting use ^ and M- notation, except for LFD and TAB
That's output from cat. If you were to run the file through 'tr -d [:cntrl:]' then LFD and TAB characters would be removed. That's the mess. Go ahead and try it if you don't believe me.
I just tested it, the man page is almost right in that CR is also not translated. Anyway, I don't want to delete all the "M-" characters, just "M- " (em minus space). That character acts like a tab on my terminal, but seems to be a tab with the high bit set.
There are no "em minus space" characters. They don't exist. That is cat's human-readable translation of nonprinting characters. If you want to remove these nonprinting characters then you have to do it by interpreted sequences (like "\a") or octal codes.
