Description of problem:
Given a PDF lacking embedded fonts which use certain characters (including → and ≥), GNOME's Evince on Fedora 36 chooses to substitute the Noto Sans font, which does not include these characters.

Version-Release number of selected component (if applicable):


How reproducible:
Successfully reproduced by two people independently.


Steps to Reproduce:
1. Boot a fresh copy of Fedora 36 (the Live version in a VM will do).
2. Open the attached sample PDF in GNOME Evince (aka Document Viewer).
3. Observe the missing characters in the second paragraph from the top of the page.

Actual results:
See attached image.

Expected results:
The missing characters should be displayed properly as → (that is, https://unicode-table.com/en/2192/).
