Hi,
Yes i know that, and becauae of that i finally fix this with aliasing in fbapi
unit Pchar = PAnsiChar
I do this only to got some results from api
I finall implementation i do this better and replace PChar in fbapi as some
internal type like PFBChar and this type for delphi i change as PAnsiChar
{$Ifdef FPC}
PFBChar = PChar;
{$else}
PFBChar = PAnsiChar;
{$endif}
Regards,
Karol Bieniaszewski

and you write, in a later post:

With recent (2009+) versions of Delphi "string" is a UTF-16
string, so PChar is a pointer to a word, not a byte. Being
such a fundamental type in Delphi you really don't want to
try and change it.
I'm not that familiar with FreePascal, but I understand its
"string" type uses UTF-8 and PChar/Char are aliases for
PAnsiChar and AnsiChar. see:
http://wiki.freepascal.org/FPC_Unicode_support
I've not been following FB3 stuff closely but I'm assuming the
API will be working with UTF-8 strings. So any attempt to
provide both Delphi and FreePascal support in example code will
need to take care to use specific types, like UTF8String rather
than just String. And PAnsiChar and AnsiChar for the string
elements.
