fonts.conf file

Description of problem: I use a fonts.conf file to make the system use
Cantarell's characters over DejaVu Sans and some of the asian Noto Sans
variants when a font doesn't have them, however, I've noticed that in Fedora,
this doesn't apply, and DejaVu Sans is still used instead of Cantarell.

Version-Release number of selected component (if applicable): 33

How reproducible: Always.

Steps to Reproduce:
1. Use my fonts.conf file
2. Open gucharmap and search for the U+2236 (ratio) character under "common".
3. Right click on it.

Actual results: It shows DejaVu Sans instead of Cantarell.

Expected results: It should show Cantarell instead of DejaVu Sans.

That looks good to me and working as expected though?

and I didn't look at the screenshot though, it is because you chose IBM Plex
Sans for rendering on gucharmap but it doesn't have a glyph for that, then just
fallback to DejaVu Sans. that's normal. because your rule in fonts.conf is to
use Cantarell as a fallback of "sans-serif" but not "IBM Plex Sans" or
whatever.
