Hit ctrl-v and tab (or ctrl-i) or ctrl-v and enter (ctrl-m).

Also, in bash at least $'\t' works for tabs and $'\n' for enter and it
does other escape codes.

Best to escape non-printables, regardless of what they are. Less suprises
that way (taking care of utf-8 fun :).

The other possibility is not to allow nul in the data and use \0 as the
seperator.
