I try to connect with firedac to firebird 2.1 character set ISO8859_1 with Delphi 10.3 Rio. Connection is ok if I use embedded fb in work directory. If there is no embedded fb and firebird server is stopped, it still connect but with : Error is character set ISO8859_1 is not defined.
How to find where are that embedded fb, which Delphi 10.3 Rio connect?
