I want to merge two PDF files but when the input filename has some special characters such as ª or º etc., it fails to merge. With an input filename like MªRose.pdf.

try
    SetLength(Arg, 7);
    Arg[0] := PAnsiChar('-q');
    Arg[1] := PAnsiChar('-dSAFER');
    Arg[2] := PAnsiChar('-dNOPAUSE');
    Arg[3] := PAnsiChar('-dBATCH');
    Arg[4] := PAnsiChar('-sOutputFile=' + output + '.pdf');
    Arg[5] := PAnsiChar('-sDEVICE=ps2write');
    Arg[6] := PAnsiChar(input);

    ExitCode := gsapi_init_with_args(instance, Length(Arg), @Arg[0]);

    if ExitCode < 0 
       then raise Exception.Create('ERROR: init_args: '+IntToStr(ExitCode));

    gsapi_exit(instance);
finally
    gsapi_delete_instance(instance);
end;

Can someone provide a solution?

  • Ghostscript is known to work with filenames using non-ASCII languages, for example Chinese. Try executing your configuration from the command shell, I expect it will work. That should demonstrate to you that the problem is your Delph interface to the Ghostscript library. I suspect that you need to convert the filenames to UTF-8 if you are going to use the API instead of the command shell. Commented Jan 21 at 9:10

    Read Using GhostScript 9.10 in Windows with Unicode characters in parameters or the docs: Both will tell you to first call gsapi_set_arg_encoding( instance, GS_ARG_ENCODING_UTF8 ); and then to use UTF-8 AnsiStrings. Oh, and Arg[0] is always ignored. Commented Jan 21 at 15:34
