Edit1.Text := 'ľščťžý';

ZTable1.FieldByName('Text1').AsString := Edit1.Text;
stored value is OK

ZSQLProcessor1.Params.CreateParam(FtString, 'T1', ptUnknown);
ZSQLProcessor1.ParamByName('T1').Value := Edit1.Text;
ZSQLProcessor1.Script.Text := 'INSERT INTO ZTable1 Values(:T1)';
ZSQLProcessor1.Execute;
stored value is OK

....
ZSQLProcessor1.Script.Text := 'INSERT INTO ZTable1 Values('+QuotedStr(Edit1.Text)+')';
....
stored value is NOT OK

Have you tried this?

ee, no

pardon, sorry
yes tried
is NOT solve this

I have Unit ZdbcInterbase6Utils.pas in:
svn://zeos.firmos.at/zeos/trunk from 11.2.2009
with ..... UTF8String(SQL) ....

IBC component:
IBCSQL1.SQL.Text := 'insert into Table1 values('+QuotedStr(Edit1.Text)+')';
IBCSQL1.Execute;
in THE SAME DB, SAME PROJECT IS OK

not solved
still bad

Can you download lastest snapshot (601) and apply that change?

It works as expected to me

downloaded, applied, instaled - 100% ok
not work
TEST.zip from mscherr:
http://zeos.firmos.at/viewtopic.php?t=2266
not work
http://www.davidplus.sk/test/test.jpg

I had you same error .. comparing Zeos trunk and my changes I found that:

Unit ZdbcInterbase6Utils.pas

function PrepareStatement(PlainDriver: IZInterbasePlainDriver;
Handle: PISC_DB_HANDLE; TrHandle: PISC_TR_HANDLE; Dialect: Word;
SQL: string; var StmtHandle: TISC_STMT_HANDLE):
TZIbSqlStatementType;
var
StatusVector: TARRAY_ISC_STATUS;
begin
{ Allocate an sql statement }
PlainDriver.isc_dsql_alloc_statement2(@StatusVector, Handle, @StmtHandle);
CheckInterbase6Error(PlainDriver, StatusVector, lcExecute, Sql);

{ Prepare an sql statement }
{$IFDEF DELPHI12_UP}
PlainDriver.isc_dsql_prepare(@StatusVector, TrHandle, @StmtHandle,
0, PAnsiChar(AnsiString(SQL)), Dialect, nil);
{$ELSE}
PlainDriver.isc_dsql_prepare(@StatusVector, TrHandle, @StmtHandle,
0, PAnsiChar(SQL), Dialect, nil);
{$ENDIF}
CheckInterbase6Error(PlainDriver, StatusVector, lcExecute, SQL);

bingo !!!!!!!

same bug as here:
http://zeos.firmos.at/viewtopic.php?t=2259

this solve also this problem:
http://zeos.firmos.at/viewtopic.php?t=2266
but,
NOT Try this:
... 0, PAnsiChar(UTF8String(SQL)), Dialect, nil); ....
Try this:
... 0, PAnsiChar(AnsiString(SQL)), Dialect, nil); ....

thanks seawolf, good work
