Yeah - that was just to give a sense of context and scale for the rest.

That'd probably be because you only have one of the fonts-noto-*
packages installed, whereas I have four of them (and we don't have any
overlap).

Going a bit beyond this for more context:

$ apt-file search /usr/share/fonts/truetype/noto/ | wc -l
2380

(So my 1847 is about three-fourths of the total, assuming no collisions.
I did also verify that every item in this count is named as being a TTF
file.)

$ apt-file search /usr/share/fonts/truetype/noto/ | cut -d ':' -f 1 | uniq
fonts-noto-color-emoji
fonts-noto-core
fonts-noto-extra
fonts-noto-mono
fonts-noto-ui-core
fonts-noto-ui-extra

Per the above, I have four of those installed: core, extra, mono, and
ui-core. By contrast, you appear to have only one installed:
color-emoji, which (according to 'apt-file show') appears to contain
only one font file - the one you reported from fc-list, above.

In my case, I got tired of seeing the "tofu" (without, I think, ever
learning that term), and went out of my way to install fonts to provide
as much coverage as I could manage. I appear to have missed one or two,
but I haven't seen any missing glyphs in rather a while.
