Errors upgrading from 7.3 to 8.1

Currently running Postgres 7.3.9 32bit on Fedora Core 1, and upgrading to PG
8.1 64bit on Centos 4.

When I load the file,
psql -U dbname < dbname.sql

I get this error:
ERROR: invalid UTF-8 byte sequence detected near byte 0x96
when inserting fields that seem to contain HTML. What could be causing this?
My understanding is that pg_dump should properly escape things so that I'm
not trying to dump/load things improperly.

The dumps are made (on the PG 7.3 server)
pg_dump -d -f $OUTPUT.pgsql $db

Are being restore with (on the new 8.1 server)
psql -U $db -e < $OUTPUT.pgsql
