invalid byte sequence for encoding "UTF8": 0xf1612220

I am trying to migrate a database from Postgresql 8.2 to Postgresql 8.3 and
getting the following error:

pg_restore: [archiver (db)] Error from TOC entry 2764; 0 29708702 TABLE DATA
originaldata postgres
pg_restore: [archiver (db)] COPY failed: ERROR: invalid byte sequence for
encoding "UTF8": 0xf1612220
HINT: This error can also happen if the byte sequence does not match the
encoding expected by the server, which is controlled by "client_encoding".
CONTEXT: COPY wi_originaldata, line 3592

I took a dump from 8.2 server and then tried to restore at 8.3.

Both the client_encoding and server_encoding are UTF8 at both the servers.

Any help will be appreciable.
