In Firefox 88.0.1 the document is displayed correct.
Comment 3 Yuri Chornoivan 2021-05-24 15:21:14 UTC
Cannot be reproduced here.

What substitution is shown in the font list on the
"Fonts" tab the window that can be invoked by the "File -> Properties" menu
item?

Can you install some neo-grotesque fonts (Arial and DejaVu)?

Thanks in advance for your answer.

Hi Yuri, I have no idea what "neo-grotesque" fonts are. But in my Manjaro I have:

- DejaVu Math
- DejaVu Sans
- DejaVu Sans Mono

but no Arial (it's a MS font, right?)

Please advise if there is any specific font to be installed for testing.

Thanks, Henrik

Must be a poppler problem (evince shows the same rendering, but mupdf renders correctly).
Comment 8 Albert Astals Cid 2021-05-25 21:22:13 UTC
Yuri you originally said it worked for you but now you say that evince also fails for you?

Can you confirm if you get good rendering with Okular?

It works for the snippet from the reporter's screenshot but does not work in the other place (see my screenshot).

> Can you confirm if you get good rendering with Okular?

The quotes from the reporter's snippet are rendered correctly in both Okular and Evince on my machine (Microsoft's Arial and DejaVu Sans substitution).

Problem on David’s Okular

I get promille and very long dashes instead. Fonts are replaced with “Arimo”.
Comment 11 Albert Astals Cid 2021-05-26 22:13:53 UTC
The file seems relatively broken, at least both mupdf and gs complain quite a bit about its fonts.

Anyhow, this is not an okular problem because okular doesn't do the rendering of pdf files, popple does.

Please report the issue at https://gitlab.freedesktop.org/poppler/poppler/-/issues

Thanks for clarification - I've created a bug report against poppler:
