It shouldn't do that.  It should replace the tab with nothing at all, so
if you have "x  y" (there's a tab there) it should become "xy".  Are you
sure it hasn't done that and you just didn't notice because the tabs
generally had spaces at one side?  Tabs you type in Emacs are often
converted to spaces, TAB usually mean "indent" in Emacs.

Type C-x 8 RET NULL RET in any buffer.  Now you have the NULL character,
cut it into the kill ring.  Then do:-
-- replace-string
--- TAB (press tab)
--- C-y (which will yank the null character).

There are probably better ways to do it.
