Use tabs (\t) and spaces (\x20) instead

Notes:
------
when restoring, ensure to have no
additional tabs and spaces included/wrapped;
for example, z_ts(z_ts('hello world')+' ')->false
and vice versa, ensure nothing gets lost;
like when using output in comments, posts --
since it gets probably trimmed; (' '->' ')
