Reading a file on Windows with psql

On Windows (Windows Server 2008), I create a file using a tool (Data
Generator for PostgreSQL), and then try to execute the script using:

psql --file="C:\PDS\TestData\populate_companies.sql" --dbname=tst --username=tst

I get an error, pointing to the first character in the file. So I open
the file using pgAdmin and I see only an "I" (the first character of
the first command in the file, which is an INSERT) in the file.

If I load the file into a Windows editor, I see that it's a "unicode"
file. If I re-save it as a "DOS" file, then psql is able to read it.

Is there a way to convince psql to read a file in "unicode" format?

PostgreSQL is 8.4.. Thanks for your help!
