FYI - here's what Sybase's bcp does:

create table fts_char(c1 char(20), c2 varchar(20));

cat /tmp/fts_char.bcp
ABC     CDE
ABC             CDE

Note that the char(20) column is *padded* to the correct width, while
the varchar() column is trimmed. I suspect that you will have to become
a little more precise for char() columns, and either pad or truncate as
needed to match the target column's width.

I've got the full Ribo trace of the session, if you want.
