--- Comment #30 from Akira TAGOH tagoh@redhat.com --- Sorry, my words weren't enough. Well, you may need to write a config like the above but replace DejaVu Sans to any of them. Unfortunately just installing them doesn't help right. I'm asking what is sufficient for alternatives of Symbol font.
Please put the following config into $HOME/.config/fontconfig/conf.d/0-symbol.conf and replacing FONTNAME to any of "Noto Sans Symbols", "Noto Sans Symbols 2", "Symbola".
<fontconfig> <alias> <family>Symbol</family> <default><family>FONTNAME</family></default> </alias> </fontconfig>
This will makes fontconfig to pick up any of them as alternatives to Symbol.
