Those aren't ASCII.

There are three places you need to get this right:
1. The database encoding
2. The client encoding
3. The encoding of the contents of the .sql file
Now, since the database is UTF8 that means it can accept the entire
range of unicode characters, including all ISO-8859-1.
PostgreSQL can automatically convert from ISO-8859-1 to UTF-8 for you,
so it doesn't matter which you have in your .sql file.
What *does* matter is that you know what encoding your .sql file is
using and that you set the client encoding appropriately.
Since you're using Java, it's probably simplest just to use UTF-8 all
the way through. Crucially, make sure you know what the character-set of
the .sql file is - any good text editor should be able to tell you / set
this.
