UTF-8 Characters Printed as Boxes

Hello!

I'm having problems with some 3 and 4 byte characters in PDFs, they come out as [] boxes. I've got the example code here, as I understand the font should have the glyph (fallback font is the same Arial Unicode MS as well) but it won't print many 3-4 byte characters. Is this just something not supported yet or am I missing something?

  Doc:=TPdfDocumentGDI.Create;
  Doc.AddPage;
  Rect := TRect.Create(10, 10, 200, 200);
  Doc.VCLCanvas.Font.Name := 'Arial Unicode MS';
  Doc.VCLCanvas.TextRect(Rect, 20, 20, '?'); // Text is either directly pasted character from http://www.i18nguy.com/unicode/supplementary-test.html#utf8 or read from .txt file
  Doc.SaveToFile('test.pdf');

Which version of Delphi are you using?

XE8 currently.

We rely on UniScribe directly for such rendering.
You may try to disable UniScribe, and see how it renders.

Tried turning UniScribe on and off with various settings, no luck. Interestingly with UniScribe on 4 byte characters render as single boxes, with UniScribe off those characters are rendered as two overlapping boxes.

Are you SURE those glyphs are part of your Arial Unicode MS ?
