echo can't be use to display arbitrary data as it expands escape
sequences (here \t for tab). Moreover, it's one of the least
portable commands, some of them even accept options (you can't
display "-n" then for instance). It's a command to avoid in
scripts except to display constant strings (litterals).
Use printf instead:
printf '%s\n' "|$1|"
