To be clear: this is not the fontconfig cache, itʼs the user-specific
directory for configuring fontconfig. I had one because I was playing
around with hinting styles at one point, and thatʼs exactly what can
cause Noto Color Emoji to fail (donʼt ask me why).

But yes, we should ask people to move both the fontconfig cache and
the fontconfig user directory out of the way (or ask them to run
FC_DEBUG=1024 emacs -Q, which will show us which fontconfig config
files are being loaded).
