You're right. Look:

1 ~> echo $IFS | dump
0000  20  9  A  0  A                                     .....

This is <space>, '\t', '\n' and '\0'. The last "A" is the '\n' printed by echo.

In bash, IFS is set to nothing.

I unset IFS in zsh and "set|grep" worked again.
Using "grep -a" also works.

Is it ok if I remove \0 from IFS?

I would like to thank everybody who replied to my message. Thank you.
