That's hilarious.  I mean, I'm not writing "Iosevka".  Why does it need
to do something like this in the first place?

I had:

<alias>
  <family>monospace</family>
  <prefer>
    <family>Iosevka Comfy</family>
  </prefer>
  <default><family>Iosevka Comfy</family></default>
</alias>

in ~/.config/fontconfig/fonts.conf file.  I've changed "Iosevka Comfy"
with "iosevka comfy".  I had also "Emacs.font: Iosevka Comfy-10" in
~/.Xresources file.  I've also changed it with "iosevka comfy-10".

But unfortunately, it's still the same.
