Has iconv been any help?

Will running the following on your file useful

http://www.gnu.org/software/recode/

It helped me with a pg_dump file in the past

I'd use recode:  http://recode.progiciels-bpi.ca/index.html
It can recode large files without needing much memory.

Hi,

I'm just guessing.

If you have a database in UTF8 and your SQL-file in some encoding so
what about doing this:

1. Connect to your database using psql
$ psql -p ... -h ... -U ... your_database

2. Set client encoding to the encoding of your SQL-file
yourdb=# \encoding your_sql_encoding

3. Load the SQL-file
\i your_sql_file
