Hi Richard,

thanks for the answer! Nevertheless, see below... ;)

OK, probably my idea of what ASCII is is a bit too vague: by ASCII I simply
meant the ISO-8859-1 charset. (Which might make further discussions about
what exactly belongs to ASCII unnecessary...?)

Eclipse (the editor which I'm using) says that the original SQL file's
encoding is ISO-8859-1, the special characters are shown correctly, also in
other text editors.

How do I set the client encoding to ISO-8859-1? As I wrote, the <sql> task
complains if I set the client encoding to LATIN1 (which is the PostGres
equivalent of ISO-8859-1 if I'm right) that the JDBC driver is not going to
like it. (And so it seems indeed.)

As I wrote in my original post, I *have* tried using UTF-8 "all the way
through" by converting the original ISO-8859-1 file to UTF-8 and calling the
<sql> task with 'encoding="UTF-8"'. It didn't help, the special characters
still became question marks. I've also set the client_encoding parameter in
the sql file explicitly and I know, i.e., pgAdmin tells me the DB's encoding
is UTF-8. (And it should be right, since *that* is able to insert special
characters)

So, to my best knowledge I got it right on all three places, and it still
doesn't work. That's why I opened the topic in the first place.

So any other idea what can be wrong here?

Thanks!
