Jason,

database (for mixed-language applications). That's why I use UTF8 as
the Character Set for my database columns and that's why I use UTF8 as
the client character set. All other Client character sets would
restrict me to the characters in ISO8859_1 or WIN1252 or whatever.
want to have control over the characters when I want/need it. For
databases that are known to be only used for German text, I will use
ISO8895_1 for the database and the client.
So if I want to have characters in, say, ISO8859_1 i specify that as
the Client character set and everything gets transliterated to that.
Same for WIN1252. But when I specify UTF8 as the Client character set,
I would like to have the "real thing".
As far as I understand things, the Client DLL (fbclient.dll) does all
the transliteration, so you just have to hand over what you get from
there?
