Or go via MS-Access/Perl and ODBC/DBI perhaps?

Well, what character-set is your database in?

You'll want UTF-8 or LATIN9 for the euro symbol. LATIN1 supports that
character-number but it is used for a different symbol.

Your first step needs to be to find out what character-set your data is in.
Your second is then to decide what char-set you want to use to store it
in PG.
Then you can decide how to get there.
