After updating tumbleweed I notice that I cannot see any numbers in certain
places. They are drawn in a outline shape and not from the right font. I found
fonts-config-20180430-181.1.noarch ->
/usr/share/fonts-config/conf.avail/59-family-prefer-emoji.conf to be causing
this behaviour and for now I deleted this file. But I lack in depth
understanding of font. Happy to do some debugging if you tell me how.

Reproducible: Always

Steps to Reproduce:
1. Visit a website with monospace font, example:
www.linux-magazin.de/ausgaben/2017/08/c/
2. Numbers rendered incorrectly
3. After removing Emoji One from fontconfig, it shows correctly
Actual Results:  
Emoji font shouldn't confuse the font used


See screenshot for wrong rendering
