We have a rather large Firebird database that was created a long time
ago (as an Interbase DB) using character set "NONE". We use it from
Java 1.4.2. by means of Interclient. The data in there is actually ISO
8859-1 (but the DB does not know about it).

We want to replace Interclient by Jaybird, but did run into a problem
with the character sets. When connecting using character set "NONE",
we can read and write, but any non-ASCII character seems to be ignored
(replaced by "?"). When we indicate ISO8859_1, it tries to convert,
which of course fails.

What can we do to achieve 8-bit transparent access to the DB using
Jaybird? Or is there a different approach that we could try?

Regards,

Andreas
