See the below screenshot.

I've tried:
- Running the program as-is
- Running
test/fetch-fonts.bash first
- Copying a different version of DroidSansFallbackFull.ttf into the fonts dir (4.5mb instead of 100kb)
- Building https://github.com/parlr/chinese-data and running with
--data ../chinese-data/src/codepoint-ruby.json
None of these options have worked without the missing glyphs being exported to svg
