So most probably the dump is latin1 (this was the clientencoding during
dumping).

That there is no error message does not mean that there is no error in the
encoding. It only means that there is no Invalid UTF8. So it is importent to
set the correct client encoding, which was used for the backup, also during
restore.

When you plan to insert non Latin1 codes into the database you have to change
the clientencoding for backup/restore to UTF8.

Have a look at chapter 20 of the manual for different possibilies to set the
client encoding.
