  I'm unable to add to PDF file some characters from Droid Serif font (attached). These characters are in the font. For example, I try to add ≠ symbol (UCS4: 8800 (0x2260), UTF8: \xE2\x89\xA0).

  What I do:

  PdfPainter p ...
  
  p.TextObject.Begin();
  p.TextObject.MoveTo( x, y );
  p.TextState.SetFont( font, 8.0 );
  p.TextState.SetFontScale( 1.0 );
  const QByteArray utf8 = qstring.toUtf8();
  p.TextObject.AddText( utf8.data() /* const char * here */ );
  p.TextObject.End();

  I don't receive any exceptions here, but in PDF on place of ≠ symbol is empty space.

  What's wrong?

• [Bug report] What is the expected behavior?

  I'd like to see in generated PDF ≠ symbol as well.

This worked for me in C++17 compilation with master (currently it's 0.11-dev):

    PdfMemDocument document;
    PdfPainter painter;
    auto& page = document.GetPages().CreatePage(PdfPage::CreateStandardPageSize(PdfPageSize::A4));
    painter.SetCanvas(page);
    auto& font = document.GetFonts().GetOrCreateFont(R"(D:\Downloads\droid_serif\droid_serif.ttf)");
    painter.TextState.SetFont(font, 18);

    painter.TextObject.Begin();
    painter.TextObject.MoveTo(56.69, page.GetRect().Height - 56.69);
    painter.TextState.SetFont(font, 12);
    painter.TextState.SetFontScale(1.0);
    painter.TextObject.AddText(u8"\u2260"); // Or painter.TextObject.AddText("\342\211\240"), it's the same
    painter.TextObject.End();
    painter.FinishDrawing();
    document.Save(R"(D:\test.pdf)");

And produces test.pdf. Can you test both 0.10.3 and 0.11-dev with that snippet in your machine?

Got it. My issue. Sorry for your time.
