For the benefit of the discussion, I'll repeat and expand on what I said
on the evince mailing list.

This document does not embed fonts, which means that poppler uses
fontconfig to locate appropriate substitute fonts.  If fontconfig can't
find the right combination of bold and italic, it will select some other
non-italic or non-bold variant.  My system, and apparently also William
Bader's system, at least show the bold font but not the italic font
because we have a bold CJK font installed.  I don't think that poppler
tries to synthesize font styles.

The pdf reference does mention that font styles can be synthesized, and
this might be what acroread is doing, so it would be nice if poppler
could synthesize bold or italic font styles.

2017-04-21 Thread William Bader 
atril (the Mate desktop version of evince, I think using poppler-0.34.0) on 
Fedora 23 gets the bold but not the italic.


pdftops-0.53.0 -level3 also gets the bold but not the italic.


pdftops-0.53.0 -level2 generates a ps that fails in ghostscript with Error: 
/rangecheck in --xyshow-- , possibly similar to 
https://bugs.freedesktop.org/show_bug.cgi?id=63963

It looks like the file does not contain the fonts.

Subject: [poppler] evince does not show chinese bold or italic

Now that Adobe has retracted support for Adobe Reader for Linux, we
use Evince as the default pdf viewer.
But we have an issue with evince for chinese text with bold, italic or both.
The font(s) used are "STSong-Light", "STSong-Light,Bold"  ,
"STSong-Light,Italic" , and "STSong-Light,BoldItalic" .

Attached screenshots show an example line with each of the fonts above,
displayed by (Adobe Acrobat Reader) acroread, and evince.
As can be seen, evince shows no difference between the lines of chinese
text.
I also attach the pdf file.
Latest tested evince version: 3.14.2 (RHEL7).

I suspect (but I'm not sure) that acroread synthesizes bold and italic
from the regular font, and that evince fails to do so.
Or could it be that additional fonts need to be installed?
Or might this have been fixed in a later version of evince?

Kind regards,
Thomas Johnsson
