right now you can only use database encoding "LATIN1" (without
euro-sign) or "LATIN10" for german text. "UNICODE" doesn't work with
umlauts, sharp s or euro-sign.
Because of missing conversion functions to win1252 (Windows default
encoding on german MS systems) you must use same encoding on client side
as for the database, or UNICODE on client side, if your
application supports it.
I prepared a patch for WIN1252 encoding on db and client side, which
will probably be included in version 8.1 (V8.0 is closed for new features).
An alternative is to use an encoding for the database, which you
normally don't use (e.g. WIN1250) in conjunction with a patched
conversion DLL (e.g. utf8_and_win1250.dll), so you can use either
WIN1250 (which represents WIN1252) or UNICODE on client side. This way I
do it until real WIN1252-support is available.
With best regards,
Roland.
