I've just been reading through the code used to build the bin/fc-cache-v6 and bin/fc-cache-v7 binaries in the core snap:

https://github.com/snapcore/fc-cache-static-builder

I think I understand what the problem is: while it is rebuilding copies of xenial's and bionic's fontconfig tools that statically link to libfontconfig, it's using the xenial version of libfreetype2 for both.

I suspect that this old freetype version does not understand all the features of the font (e.g. the scalable colour emoji), so the generated cache also misses them.
