My problem is solved too! And I can confirm that the reason was in wrong codepage assignment "1252" = "c_1251.nls", as edward_1 posted above.
Thanks a lot!

I've tested with new version of SynCommons - the problem still persists.

Here is dump of fAnsiToWide array after executing this code:

constructor TSynAnsiFixedWidth.Create(aCodePage: cardinal);
.........
  if PtrInt(inherited AnsiBufferToUnicode(U256,A256,256))-PtrInt(@U256)<>512 then
    raise ESynException.CreateFmt('OS error for %s.Create(%d)',[ClassName,aCodePage]);
  move(U256,fAnsiToWide[0],256*2);
..........

when result PDF is OK:
(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 8364, 129, 8218, 402, 8222, 8230, 8224, 8225, 710, 8240, 352, 8249, 338, 141, 381, 143, 144, 8216, 8217, 8220, 8221, 8226, 8211, 8212, 732, 8482, 353, 8250, 339, 157, 382, 376, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239, 240, 241, 242, 243, 244, 245, 246, 247, 248, 249, 250, 251, 252, 253, 254, 255)

Thank you for response! Will try on Monday (problem PC is at work).

BTW, I encountered one more bug - "Access violation" on EMF with one specific non-standard font. I have located place in code where violation occurs, but can't understand how to change code to avoid this error.
Can I send you test EMF and problem font?

Thank you!

MrHide

Checked it on another XP machine - OK! Even on Win2K is OK!
Thus, the problem is not in the OS used.
I decided to debug thru PDF engine and to compare variables and arrays content, and finally found out - the difference is in how MultiByteToWideChar works, which is used in TSynAnsiConvert.AnsiBufferToUnicode function (in SynCommons.pas).

Any ideas how to fix this problem?

Here the test files:

Test metafile  -  https://www.dropbox.com/s/mpu4haw9j0k4yuk/text.emf
PDF created in Win7 - https://www.dropbox.com/s/1frm048a1q08j5h/text_win7.pdf
PDF created in WinXP - https://www.dropbox.com/s/p39k76v1utghh … _winXP.pdf

and code:

procedure TForm1.Button1Click(Sender: TObject);
const
  InputFileName = 'text.emf';
  OutputFileName = 'text_win7.pdf';
var
  Pdf: TPDFDocumentGDI;
  Emf: TMetafile;
begin
  Emf := TMetafile.Create;
  try
    Emf.LoadFromFile(InputFileName);
    Pdf := TPdfDocumentGDI.Create;
    try
      Pdf.AddPage;
      Pdf.Canvas.RenderMetaFile(Emf, 1, 0, 0, tpExactTextCharacterPositining);
      Pdf.SaveToFile(OutputFileName);
    finally
      Pdf.Free;
    end;
  finally
    Emf.Free;
  end;
end;

Check the embedded fonts in both PDFs.
What do you think?

Yes, I tried both, still no effect.

Hello!

I create PDF from metafile (using RenderMetaFile function) which contains cyrillic text.
If PDF created under Window 7 everything is OK, but under Windows XP (SP3) it's shown using east-european symbols.
I compared embedded fonts (in Acrobat Reader) and found out that PDF created under Windows 7 contains one font more, to be exact:

  • TimesNewRoman,Bold
    Type: TrueType(CID)
    Encoding: Identity-H
    Actual font: TimesNewRoman,Bold

while PDF created under Windows XP only:

  • TimesNewRoman,Bold
    Type: TrueType
    Encoding: Ansi
    Actual font: TimesNewRomanPS-BoldMT

Switching properties like EmbeddedTTF, EmbeddedWholeTTF etc. and setting CodePage has no effect.

Can you help me? What else should I try to force SynPDF generate the right files under Windows XP?

P.S. I'm using Delphi 7 and the latest "unstable" version of SynPDF from code repository.

Thank you in advance!
