Changing the terminal code page won't do anything, it's probably the data
that are in a different encoding.
I don't know enough about MySQL to know which encoding it uses when dumping data,
but the man page of "mysqldump" tells me:
--set-charset
Add SET NAMES default_character_set to the output. This option is enabled by default.
So is there a SET NAMES command in the dump? If yes, what is the argument?
You will have to tell PostgreSQL the encoding of the data.
As Kevin pointed out, you can do that by setting the environment variable
PGCLIENT ENCODING to the correct value. Then PostgreSQL will convert the
data automatically.
