I'm using Delphi 2007 and have a problem when the database foldername contains an scandinavian character ( ö ), IBDAC won't connect to the database.

Please provide the exact error message text, which you receive.

I/O error for file C:\F?RETAG\FILENAME.GDB
Error while trying to open file
Path not found

? shows where character ö should be ( error msg does not have ? chararcter, it has 2 chars Ä~ ).

You can easily test it, create an folder named FÖRETAG and put a database there.

The issue when the the database foldername contains international characters is not related to IBDAC, but is due to the firebird client library specificities. You can make this sure by trying to connect to the database using the standard components - FireDAC. Unfortunately, we can't affect this behavior.

I'm using InterBase, not Firebird.

This behavior is typical for both InterBase and Firebird.

I'm using D2007 so I don't have Firedac but TIBDatabase works fine.

What has changed from IBDAC 3.x version to 5.x bc it works with older IBDAC version ?

While investigating we have detected, that the latest version of IBDAC 5.7.25 has the similar behavior with the IBX and FireDAC components.
Please, make sure, that you are using the latest version of IBDAC 5.7.25 and the same version of the client library InterBase with IBDAC and IBX. If you see any difference in the behavior between the IBDAC 5.7.25 and IBX components, please, provide the used InterBase version and the set locale on the client's computer.

IBDAC is version 5.7.25
Same Interbase version (2007) is used.
Locale is FI

Thank you for the information. We have reproduced and fixed the issue. This fix will be included in the next build of UniDAC, that we plan to release within a week.

Great, thank you.

The new IBDAC version 5.7.26 with a fix for this issue is available for download now.
