Well, then it is a documented one. It surprised me at first, but then, it's not that surprising at all.
Char fields are right padded with blanks. So empty() does not know whether you inserted space(0) or space(4) for char fields. But for memo fields it does.

It's all described in the help.

Still, it's tricky
create cursor ppp(ppp M)
insert into ppp (ppp) values (space(4))
?empty(ppp) && FALSE
qqq=ppp
?empty(qqq)  && TRUE  !!
