Postgresql - cwstring

[jaromir]

Hello,

My new library request to add cwstring unit to uses statement.
It is unix os - freebsd. After cwstring uses add my zeos connection writes wrong national data.
Reading is correct but writing is corrupted. I tried latest 7.2.4.
Without cwstring add everything works fine.

Any suggestion please ?

Best regards
Jaromir

Hello Jaromir,

what version of FPC do you use? Do you use Lazarus? Which Version? Which version of PostgreSQL are you on? Could you share a little sample application and a database script with us?
Best regards,

Hello Jan,

I use plain fpc 2.6.4. Tomorrow I try 3.0.2 and I try to make testcase. What kind of test console app will be best ?
This is utf/ansi conversion problem so console entered data depends of console settings. National data at source code ?
I can’t make gui app.

Hello Jaromir,

it seems strange to me that this should only be an issue with the cwstrings unit. It could be that Zeos with FPC assumes you use UTF8 although maybe you don't? What is the setting of the ControlsCodePage ZConnection property?

Using FPC 3.0 could help too. It has ways to make it use UTF8 internally for almost anything and do the conversion to the system code page for you whenever it interacts with the system.

Any example application will do. Please inclue a create script. Maybe it makes sense to provide information on how you compile that application and what codepage you use by default. Also it would be good to know how you do your debugging. Do you use the FPC console IDE?

With best regards,

Jan

Jan,

Thank You for Your support. At least we remove cwstring require from our new library.
So problem is not resolved but not exists at this moment. I hope we will have spare time for this problem return.

Best regards.
