'\0' somewhere in the middle of string.

String as a clumplet data.

This is seems to be a data generated by a fb itself ?

At least Im not aware of touching the clumpet data by the code Im using.

Could it be a firebird incompatibility issue or what could it be?

No, parameter blocks are coming from outside.
Most likely in your program you put a string in UTF-16 encoding where ANSI or UTF-8 is
expected.

Sorry, Im kind of newbie to firebird. What do you call a parameter block in this context?

As far as I'm aware it doesn't cover parameter blocks at all. What
specifically are you referring to here?

Database parameter buffers (or blocks) are what a client application
uses to specify connection properties to fbclient/Firebird server when
connecting. This might be hidden from you by a driver layer in your
programming language that converts from a suitable representation in
your language to the one expected by Firebird.

Dimitry suspects that you have a parameter block value that contains a
NUL byte (0x00) in the middle of a string. As this is a non-printable
character, you might not see it.

However, we're just guessing here. With more details, like a
reproducible, but minimal example, we might be able to help you better.

Anything wrong with the parameter block ?

Hmm, I couldnt believe, it was so trivial ...

I was using on windows fbclient 4 beta 1 trying to connect to fb server beta 4 .

 This produced the above message.

[Pro Turm]

ps sorry small typo

fblient 4 beta 1 -> fbserver 4 beta 2

was the problem.
