Hey!
DejaVu Sans provides some emojis in B&W. In Debian, we have Noto Color
Emoji which can be used for emojis. Unfortunately, when the base font
is DejaVu Sans, the fallback doesn't happen. Fontconfig makes it
difficult to avoid using some range of a font and prefer another
font. Most hacks will add the emoji font as a fallback:
<alias binding="weak">
<family>sans-serif</family>
<prefer>
<family>emoji</family>
</prefer>
</alias>
<alias binding="weak">
<family>serif</family>
<prefer>
<family>emoji</family>
</prefer>
</alias>
<alias binding="weak">
<family>monospace</family>
<prefer>
<family>emoji</family>
</prefer>
</alias>
However, this doesn't work with DejaVu Sans. If we use "strong"
binding, too many characters are replaced (like figures). A solution
is to just blacklist DejaVu Sans:
<selectfont>
<rejectfont>
<pattern>
<patelt name="family">
<string>DejaVu Sans</string>
</patelt>
</pattern>
<pattern>
<patelt name="family">
<string>DejaVu Serif</string>
</patelt>
</pattern>
<pattern>
<patelt name="family">
<string>DejaVu Sans Mono</string>
</patelt>
</pattern>
</rejectfont>
</selectfont>
As an alternative, Arch Linux provides an emoji-less DejaVu Sans. This
would also work for Debian. Would it be possible to follow the same
path?
