Emoji not inserted into font using sbix format

[pj]

Hi there, I'm trying to add some emoji to the apple emoji fonts using the sbix format, but it doesn't see to show up. I've tried extracting files, injecting the files, then extracting again and comparing the results and it doesn't seem to show up. I compiled the jar file from latest master.

Script I'm using is:

#!/bin/bash

rm -rf 'Apple Color Emoji.ttf.sbix.d'
rm -f 'Apple Color Emoji.ttf.sbix.ttf'
rm -rf 'Apple Color Emoji.ttf.sbix.ttf.sbix.d'
java -jar ../bitsnpicas/main/java/BitsNPicas/BitsNPicas.jar extractsbix Apple\ Color\ Emoji.ttf

rsync -a ./resized_memes/* ./Apple\ Color\ Emoji.ttf.sbix.d 

java -jar ../bitsnpicas/main/java/BitsNPicas/BitsNPicas.jar injectsbix Apple\ Color\ Emoji.ttf

java -jar ../bitsnpicas/main/java/BitsNPicas/BitsNPicas.jar extractsbix Apple\ Color\ Emoji.ttf.sbix.ttf
diff -r Apple\ Color\ Emoji.ttf.sbix.d Apple\ Color\ Emoji.ttf.sbix.ttf.sbix.d

Output is:

I would expect to see files in the other folder that weren't in the first.

Thanks for your work! I'll keep seeing if I can debug what's happening.

I think the issue you're having is that the TTF you inject the emoji into has to already have glyphs for the characters you want, and I don't think Apple Color Emoji has U+F0000.
